The AST cannot distinguish between (x) and x. Adding a check
to the VM compiler that detects syntactically illegal assignments
like (x) = 0. The existing checks only analyze the AST so we
didn’t detect some illegal cases.
Looking at the source to detect syntactically illegal left hand
expressions is a bit ugly because we can’t easily look at
previous tokens. This change rewinds the token iterator a few
positions and then moves forward to check whether the last token
of the expression is an identifier or a closing bracket ].
Added new test. We did not have a single test case for this :)

The AST for static getters differs between parsing the first time, and
subsequent parsings. This leads to a mismatch in deoptimization-ids
between the optimized and the unoptimized code.
This CL avoids creating different ASTs for the same static getters. To allow
better inlining of these getters, the initialization expression is wrapped in a
hidden static initializer-function. As a result the size of such getters is
constant and does not depend on the initializer expression.

Implement check that member names do not conflict with type
parameters. Simplify name checks in class namespace.
Mark typevariable_mirror_metadata_test as failing now that we
report the proper compile time errors. (The test expects no errors.)
Some co19 tests expect a name conflict between a setter X= and type
parameter X. This is still in flux from a language perspective. This
change list does not introduce an compile error for this case.
Fix for issue 13701.

By inserting the necessary checks for null inside the callee
at the AST level, the code generation of == operations can be
greatly simplified.
This is a performance-neutral change and a step for allowing
generic inlining of arbitrary == methods. So far we could only
inline them for a common set of types in the flow graph
optimizer.

Update VM to latest spec. Referencing a name that is imported
from more than one library is no longer a compile-time error.
If one of the sources of an ambiguous reference is a dart library,
the dart library declaration is automatically hidden.
Also fixes a bug where looking up a getter name in a library
found the getter even though the name is filtered out in the
'hide' combinator.
Long-term we should fix the need for repeatedly convert between
the mangled getter and setter names and the untangled name.
Fixes 12915, 12913, 12724.

When nesting try-finally, the outer finally was incorrectly executed
twice under certain conditions (a return in the inner try-block and a outer
finally-block that ends with throw)
This was because finally-code was inlined at return/break/continue statements
and it was associated with the wrong catch-handler when compiling.
This CL tracks indices of try-blocks in the parser so that each inlined
finally block has the correct catch handler index.

Until now there was a large discrepancy between
x.f() and
(x.f)()
This CL makes x.f() as fast as (x.f)() by automatically
generating a intermediate dispatcher function that loads
the field and invokes the result as a closure.
The approach resembles the one taken for fast noSuchMethod
invocation and reuses the same per-class cache
of dispatcher functions.
It also fixes a bug in the debugger so that VM-generated
implicit dispatcher functions (like for noSuchMethod, or
field-as-method invocation) don't show up the debuggers
stack trace.

This CL fixes a performance bug with noSuchMethod and named parameters. It also
simplifies the platform-specific code by removing special casing for the
noSuchMethod-dispatcher functions in the flow graph compiler.
Before using named optional parameters would still go through the slow
runtime in certain conditions: When running without inlining, or when
the dispatcher function was not inlined because of e.g. inlining size
heuristics, noSuchMethod would be slow if invoked with named parameters.

On each call that triggers a noSuchMethod invocation we
attach a custom dispatch function that allocates the
invocation object and invokes noSuchMethod. This dispatcher
is compiled and optimized like a normal Dart function.
Similar to method-extractors, these implicit dispatchers
do not show up as normal functions.
As a first step this CL only handles invocations of getters
and methods with no like o.foo or o.foo(). This CL gives
a >25x speedup of such noSuchMethod invocations. Calls with
multiple arguments still go through the slow path.
