Faster invocation of fields as methods.
...
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.

If a method is invoked with a mismatching number of arguments, we don't

can only invoke noSuchMethod and would not work if the method
is invoked with correct arguments at a later point.

Optimizing noSuchMethod invocation with no arguments.
...
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.
