Erik Ernst 473f2c9a60 Eliminated usages of "field" in the spec. 
It turned out to be "instance variable" or "static or instance
variable" in all cases. I considered writing "member variable" for the
latter, but we would then need to introduce that phrase somewhere, and
maybe refer to it at each usage, which would be more verbose.

Fixes #24333.

Lasse Reichstein Holst Nielsen 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.

Lasse R.H. Nielsen 6e6ff496ed Allow rethrow to end a switch case. Allow braces around switch cases. 
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.

Lasse R.H. Nielsen 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.

Lasse R.H. Nielsen 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.
