Note that the current solution is not final as it may not be correct in more
complex cases not yet covered by language tests.
The final solution will require a 'trail' instead of a simple mark bit to
prevent operations involving recursive types to diverge.

zra@google.com daf539e2f9 Fixes a couple problems with GC of unoptimized code.
1. Instead of making a pass before the Marking phase,
   this change does not visit code pointers in functions
   during marking. Then after marking, if the code has
   still not been marked, code pointers in functions
   are nulled out.
2. Since code pointers in functions may be nulled out,
   functions are no longer used as proxies for code in
   deoptimization info.

fschneider@google.com ce9573722c VM: Fix checked mode crash (issue 13831).
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.

fschneider@google.com 13b7b7242a 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.

fschneider@google.com f260416fb8 Support fast noSuchMethod dispatch for any number of arguments.
Until now, the fast dispatch was only available with getters and
zero argument methods.

This CL generalizes the approach to any number of arguments. The
dispatcher functions that are auto-generated by the compiler
are not attached to the class anymore. Instead the dispatcher
is only stored in the IC data of each call site. Each class
contains a cache of dispatcher function that map
(name, arguments descriptor) => dispatcher.

This also fixes a bug where the VM report a wrong error message
when throwing a NoSuchMethodError.

fschneider@google.com 0bf7251d1a Reland: Optimizing noSuchMethod invocation with no arguments.
This is the same CL as https://codereview.chromium.org/17315008/ with
one bug fixed:

If a method is invoked with a mismatching number of arguments, we don't
add a no-such-method-dispatcher function since the dispatcher currently
can only invoke noSuchMethod and would not work if the method
is invoked with correct arguments at a later point.

I extended the test to cover that case.

fschneider@google.com ab1981b421 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.

This CL temporarily remove deoptimzation history which was put in to prevent
repeated deoptimization caused by loop invariant code motion. It caused
illegal code motion under certain conditions.
