This adds the providesSymbol method to DynamicLibrary. It returns
whether the library contains a function with the given name.
As per dlsym(3), it is valid for dlsym to return nullptr in a success
case if the symbol actually has a NULL value. So I've changed the logic
to check for dlerror() after we invoke dlsym(), both in the existing
lookup and in the new method.

Now that we have an AST and visitor support for the FunctionReference
structure (which represents `Expression<TypeArguments>` for various
kinds of expressions), we no longer need to error recover this as a
FunctionExpressionInvocation with synthetic arguments. The resolver
still doesn't resolve the syntax properly, but that's ok because it's
not permitted in valid code (for now we just treat it as having type

On IA32 arguments are passed in registers. When a struct is returned
by value, a pointer is passed in on the stack containing the address to
which the return value is written. We did not account for this pointer
in the stack-height calculation.
This problem only surfaced when there are no arguments to the function.
Because if an argument is passed it has a higher stack height than the
pointer for the result being passed in.

However, fields which already had been transformed are indistinguishable

So instead of re-reading the information from the fields, for already
transformed structs, we read the information from the

Expandos collide after a hot restart. This currently fails because
the DDC implementation uses a static field (_keyCounter) to compute a
unique name for each expando. After a hot-restart the counter gets reset
and keys get reused accidentally.
A hacky fix would be to ensure this field is not reset after restarts,
but a more robust fix would be to use a weak map implementation like
dart2js does.

There was a rare mismatch between arguments and parameters when
inlining a constructor body.
The full arguments at the call site of a constructor body (always in a
generative constructor factory) and the parameters at inlining would
not agree on needing a 'box' for the constructor's closed-over mutated
variables (parameters and locals) when the box was needed only for
locals closed over in an assertion.
The fix is to make the condition for accepting a box match the test
for generating the box in the caller.

Safari has a bug that makes it a syntax error for a function name
to overlap with names of parameters in functions with default
parameter values.
This CL changes DDC to generates code to circumvent this issue
when emitting top-level methods. Fortunately, the Safari bug
doesn't trigger with ES6 methods, so we don't need to do anything
for Dart instance methods.
The only other occurrence of named functions in DDC are
`function*` generators that we emit. Those take no arguments,
so we don't need any additional renaming there.

A multitest section marked "dynamic type error" or "checked mode
compile time error" didn't actually do anything. It was silently treated
as "ok", which makes for a very confusing looking test.
Fixed the only remaining four tests that used "dynamic type error".
The other outcome was not used by any test.

Previously, Code objects of invisible functions were retained
in order to omit frames corresponding to such functions from stack
traces when stack trace is printed.
This change drops Code objects of invisible functions. That also
means that frames corresponding to such functions are no longer
skipped in binary DWARF stack traces.
In order to account for that, DW_AT_artificial attribute is added to
generated DWARF debug information to mark invisible functions.
Stack trace decoding now looks at this attribute and skips those
frames when symbolizing stack trace.

Heap size of snapshot objects -4.2% (arm), -4.4% (arm64).

The CFE implementation of "why not promoted" functionality for
non-promotion of `this` doesn't associate the context message with any
location information, because there is no relevant location to cite.
For example, the output can look like this:
tests/language/why_not_promoted/this_error_test.dart:16:10: Error: Property 'isEven' cannot be accessed on 'int?' because it is potentially null.
Try accessing using ?. instead.
this.isEven;
^^^^^^
Context: 'this' can't be promoted.
See http://dart.dev/go/non-promo-this
The test runner assumes that all messages have a location, so it
wasn't picking up on this context message at all. This CL avoids the
problem by having the test runner associate any location-less context
message with the error above it.
(Note that the analyzer doesn't have this problem; all of its context
messages have locations).

Marks `Function` as an extensible type so that DDC knows to use the
symbolized version of the equals operator.
The `Function` class at runtime already has its equals method attached
as the "symbolized" version. Consider `a == b`. When DDC knows `a` is
statically a raw `Function` and non-nullable (more likely with sound
null safety) the generated code should call the symbolized equals
member ex: `a[$_equals](b)`. Without this change the generated code
would be `a.equals(b)` and fail at runtime because the method does
not exist.
With this change co19_2/LibTest/core/Function/operator_eq_A01_t01

Previously, if a type mismatch occurred on a named argument, e.g.:
int.fromEnvironment('foo', defaultValue: 'BAD')
the error would be reported on the entire NamedExpression
(`defaultValue: 'BAD'` in this example). Now, the error is just
reported on the expression (`'BAD'` in this example). This makes the
analyzer behavior more self-consistent (since now assignability errors
are now consistently reported at the site of the expression that can't
be assigned). It also makes the analyzer behavior more consistent
with the CFE.
This will make it possible, in a follow-up CL, to eliminate a lot of
the inconsistencies between analyzer and CFE in the "why not promoted"
ID tests.

The DateTime conversion to local time amounts to solving an
equation, finding an offset where the current local time is that offset.
The current approach doesn't actually do that, it just tries to simulate
the JS approach, with a tweak to avoid DST change issues, but that tweak
assumes that all time zone adjustments are one hour changes.
This CL should work correctly for time zone changes of up to one hour,
but might still fail for changes of more than one hour.
It works by trying more offsets, which obviously has a performance cost,
which depends on how efficient the operation system is at providing
the local time zone for a specific milliseconds-since-epoch.

I'm not sure if the output truncation was ever practically useful. But
it causes problems now that we have a CFE test that wants to validate
that the CFE can produce many errors in one go.
I thought about allowing a test to extend the truncation size, but I
figured the simplest fix was to just not truncate at all and make the
test runner a little simpler. Also did a little clean up on this
ancient code while I was at it.
Fix#44493.

Previously, FFI store could use kUnboxedUint32 for value being stored
via 8-bit or 16-bit StoreIndexed instruction. However, such
StoreIndexed instructions require kUnboxedIntPtr representation.
Due to the mismatch in the representations, SelectRepresentations
pass inserts a speculative (deoptimizing) IntConverter instruction,
which cases crash in AOT mode. Similar problem exists for FFI loads.
This change corrects representation when unboxing value in the body
of FFI store intrinsics and when boxing the value in FFI loads,
so representation of the value matches representation required by
StoreIndexed / returned by LoadIndexed.

This is clearer because:
- The use of "could not be promoted" is consistent with the other "why
not promoted" messages.
- We avoid speculating about whether the variable might be assigned a
null value; this should help avoid confusion in cases where the user
can see that assigning a null value is impossible, but promotion
still fails.
- We avoid the phrase "intervening write", which is a little too
erudite.

This changes the span reported from the _receiver_ to
the _use_ (method name, property name, operator token).
I think this change is overall an improvement.
Specifically, its a great improvement for cmdline
output, where the receiver and the "use" are on
different lines.
One possibly weird change is that if the operator is `[]`,
then I only highlight the `[` character. I don't know if
there is a better place, and I think this is fine.

Before value is stored into Float32List, it is converted to 32-bit
float using DoubleToFloat instruction. If allocation sinking
eliminated the allocation of Float32List but we need to deoptimize,
the list is materialized and elements are filled. In such case,
we shouldn't perform double->float conversion as it already happened.
This change also updates the assertion in DoubleToFloatInstr::Canonicalize
which verifies that DoubleToFloat instruction can be used only
in certain cases.

Elimination of redundant type cast 'x as Function' where x is
a function type (such as 'void Function(int)') is not correct because
it changes semantics of a function call if such expression is
used as a receiver.
"Function" static type of receiver allows arbitrary function calls,
while known function type of the receiver means the call doesn't
need to check parameter types. Static type of receiver is currently
not stored in kernel AST but calculated from the receiver node,
so replacing 'x as Function' with 'x' changes static type of
the receiver from "Function" to function type.
