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.

Allow the debugger to inspect local variables from optimized and

inlined frames.
------------
Most remaining deoptimization code from the code generator moves to
DeoptContext. This allows the code to be reused by the debugger.
There is some rework of the code along the way. The remaining code in
the code generator is simpler.
Implement the ability to deopt a frame to an Array. Each inlined
frame accesses its locals from this array at some fixed offset.
Refactor the Debugger::CollectStackTrace code. New code is int
Debugger::CollectStackTraceNew. There is a flag --use_new_stacktrace
which can be used to revert back to the old version. I intend to
remove this flag shortly, after any dust clears.
Added a unit test which makes sure that we can inspect locals from
optimized and inlined frames. Tested this code in the dart editor
debugger as well.

Change resolving of instance methods to check early for name mismatch.
...
The names of actual arguments are checked at resolving time
for a mismatch instead of deferring this check to the function
prologue (emitted as part of the CopyParameters() prologue).
For example:
class A {
foo({a:42}) => null;
}
main() {
var a = new A();
a.foo(b:123); // noSuchMethod: no named parameter named "b".
}
This enables e.g. fast noSuchMethod invocation in the case
of a named argument mismatch.
It also makes the function prologue for instance functions that
use optional parameters shorter by omitting the check for a
name mismatch there.

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.

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.

Remove skip_static_calls_ as it uses an obsolete way to check for uncalled static calls. Will be replaced by ICData tracking.
...
Add two different PCDescriptors to differentiate between optimized and unoptimized static calls (the former loads args. descr, the later loads ICData before calling).
Populate static call's ic_data field when optimizing.

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.

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.

Scale the OSR optimization threshold by loop nesting depth.
...
For on-stack replacement (OSR), code quality is better if we optimize at
the outermost hot loop. Track loop nesting depth and scale the
threshold based on the loop depth to prefer outer loops over inner ones.

Reapply "Initial implementation of on-stack replacement (OSR)."
...
This reapplies SVN r24024 with a bugfix.
After OSR compilation, restore the pre-OSR code (which might be already
optimized) rather than the unoptimized code (which might have its entry
patched). When the optimized code entry is patched it is only safe to call
it as a static call, not as an instance call.
