8562c8ff1b Adjusted spec of initializing formal type annotation 
During migration of lib/mirrors/initializing_formals_test.dart to lib_2
it became apparent that strong mode makes it an error to have different
type annotations on an initializing formal and the corresponding field.
The language team discussed this and decided that we will take a middle
way: These type annotations can differ, but the initializing formal
must have a subtype.

This CL adjusts the spec to say that. In line with the rest of the
spec it is still a static warning (we will migrate all the static
warnings to errors as a separate step).

c15eed1269 Added metadata to new function type syntax parameter specifications 
In https://github.com/dart-lang/sdk/issues/30732 the concern was raised
that the new Function type syntax does not support metadata on
parameter specifications (i.e., on normalParameterTypes and on
namedParameterTypes).

The implication of adding support for metadata in these locations is
that `@required` can be used on function types, which is the motivation
for submitting 30732.

We have always had support on parameter declarations in function typed
parameter declarations (`void foo(@A() int f(@A() String s))`), so in
this sense there is no new semantics to worry about (Lasse: "it doesn't
mean anything anyway!").

This CL modifies the generic-function-type-alias.md informal spec to
include this kind of metadata support.

c620e827b7 Don't say that the Invocation object of setters/getters returns const map/list. 
Currently the spec says that namedArguments of, say, a setter Invocation must
return the `const{}` map. That's badly typed for Dart 2(it should at least
be `const <Symbol,Object>{}`) and unnecessarily specific.
This change just requires the object to be empty and unmodifiable.

Also remove the spec handling invalidly overridden noSuchMethod.
That's not longer possible in Dart 2.

00e98af7ef Adjusted the optional-const/new specs. 
The informal specifications of optional-const and optional-new used to
be incomplete, and this CL adds missing parts (transformation rules for
lists and maps, and for `assignableExpression`).

This version of the documents preserves the property that no `const` is
added without immediate syntactic justification.

The alternative (where `const` is used also in other contexts where
either `const` or `new` must be added, just because we can do that)
is not specified here, that'll be another CL. The corrections done in
this CL will be needed, anyway, so I separated the two.

e329e1ce29 Don't allow function values in assert tests. 
Currently you can write
  assert(() { ... });
and the function will be called and the return value used as the assert test.
This feature isn't really worth its own complexity - if you want to get the same effect, you can just write all the function:
  assert(() { ... }());
With asserts in const initializer lists, where the function call is not possible anyway, the feature went from being not very useful to being actual an complication and exception for users to remember.

81f8ea0a0a Fix unintended spec change: Final fields not being initialized is only a warning. 
A recent spec change made it an error, but the existing spec didn't actually
say that - it's one of the few warnings that do not correspond to e runtime
error.

843bb96813 Change how the language specification describes control flow. 
Changed to compositionally describing how an expression or statement can
complete (normally, throw, return, break, continue), and propagating the
completion to the surrounding statements handling those behaviors.

This should not change the current behavior except in a few cases where
the existing specification was vague, misleading or just wrong.

Actual changes:
- The super call in an initializer list is now always called at the end,
  even if it is allowed to be written earlier. This matches existing
  VM behavior.
  Initialization of initializer expressions are specified
  as part of constructor execution, not something happening
  at the `new` operator.
- The cancel call to a stream subscription when exiting an async for-in
  loop is now made explicit, and its returned future is explicitly
  awaited for.
  Previously it was unclear what happened with that future.
- Pausing a surrounding async-for loop has been added everywhere
  the body of the loop can suspend, just before the suspension.
  The loop subscription is not resumed until reaching the end of the body,
  which is equivalent to resuming it after each suspend
  and then pausing it again when the synchronous execution reaches
  the next suspend.
  So, easier and doesn't change the behavior of the loop itself,
  but it's a visible change if you check the onPause/onResume
  of the loop stream.
  Spec now recognizes that the pause call may throw on an invalid
  implementation of StreamSubscription.

Add `rethrow` as one of the statements that are allowed to end a switch case
without a warning.
Change wording to not claim that `throw` is a statement.
Also allow wrapping case statements in a block statement without causing
more warnings. Currently, a `case 4: { break; }` is required to warn because
the last statement is a block statement, not a break statement.

cc6d93b57c Make it a compile-time error if a library has part "uri"; twice for the same uri. 
If the part declaration is non-empty, it will always cause a compile-time error anyway due to duplicate declarations in the library scope. This just makes it explicit that it's an error in all cases, and avoids the special case of the empty part file being silently accepted until you put something in it.

16d806b0aa Make the spec specific about the return type of sync*/async/async* function. 
Now requires the type to be a supertype of `Iterable<T>`/`Future<T>`/`Stream<T>`
for some `T`. This allows, say, all `Future<T>` return types for `async` but
disallows using a different class implementing `Future`:
```
MyFuture foo() async {}
```
gives a static warning (error in Dart 2) because the return type is statically
known to be unsatisfied.

2a0cc74db1 Expand the definition of potentially constant expression. 
The current definition requires the expression to be valid and
compile-time constant if constructor parameters are considered
compile-time constants with types appropriate for their context.

This is necessary but not sufficient, so this CL adds the further
requirement that the expression must also be a valid (not necessarily
constant) expession if the parameters are considered non-constant
variables.

This rules out the case:

    const C(x) : y = const [x];

where the current specification would, technically, allow it as a
potentially constant expression and therefore be a valid const
constructor. In practice it would never work if the constructor is
used with "new" instead of "const".

This is not really a specification *change* - existing implementations has this restriction anyway.

Addressed the concern of #24970.

93f4f00719 Working insertion of hash values; added a few labels in spec 
Hash values are now computed for each "paragraph" starting with \LMHash
(which includes subsequent grammar, dartCode, itemize blocks, but stops
at \section-like commands).  Now addlatexhash.dart expects three arguments
(first the source latex file, then the destination simplified and
hash-value-annotated latex source file, and finally a file name used to
create the list of hash values emitted).  Adjusted testing accordingly.
Added a test for robustness of the hash value generation: It is checked
that lots of different "unimportant" changes make no difference for the
generated hash values (e.g., we can add/remove comments, change white
space, add \commentary{..} etc. without changing the hash values).

In order to ensure that all "structure" commands in the spec have a label,
I added an \LMLabel{..} a handful of places, following the style which is
used throughout the spec.

In dart.sty, the \renewcommand that made \LMHash{} produce a fixed
hash value has been removed such that the actual hash values are now
inserted into the generated spec PDF/DVI file.  Tests have been adjusted
to handle this difference between the spec with and without hash values
when comparing the two.

9570a582eb Working insertion of hash values; added a few labels in spec 
Hash values are now computed for each "paragraph" starting with \LMHash
(which includes subsequent grammar, dartCode, itemize blocks, but stops
at \section-like commands).  Now addlatexhash.dart expects three arguments
(first the source latex file, then the destination simplified and
hash-value-annotated latex source file, and finally a file name used to
create the list of hash values emitted).  Adjusted testing accordingly.
Added a test for robustness of the hash value generation: It is checked
that lots of different "unimportant" changes make no difference for the
generated hash values (e.g., we can add/remove comments, change white
space, add \commentary{..} etc. without changing the hash values).

bf339367c3 Introduced hash valued location markers in the spec 
Introduced support for adding SHA1 hash valued location markers
at several levels in the language specification, added long explanatory
comment at the end, added a script 'addlatexhash.dart' to normalize
spacing, remove comments, etc., in the spec, such that the hash values
are more robust than they would be with a direct usage of the spec.

The script passes the "dvi2tty test", that is, when the location markers
are empty, the resulting *.dvi files created from dartLangSpec.tex and
from the version processed by the script give rise to the same text via
dvi2tty, i.e., the script does not destroy the spec.
