fschneider@google.com ba0f59d1bc Polymorphic inlining for some recognized methods in the optimizing compiler.
The optimizing compiler currently recognizes a certain frequent native methods
like array length or string length and provides an inlined implementation.
Inlining does currently not work for polymorphic call sites of these methods.  
This CL enables also polymorphic inlining in the case of .length getters for
arrays and strings.

1. The method is recognized at flow graph build time. The builder creates
 the body of the method for both compilers (non-optimizing and optimizing).
 Native methods that are not recognized, are translated as before using a NativeCall
 IL instruction.

2. The flow graph inliner handles recognized methods in the same manner as normal methods.
Until now intrinsic and recognized method could not be inlined. This CL enables it.

3. There is no need for an intrinsic assembly implementation because recognized methods
have an IL implementation that does not call into the C++ runtime. I left the intrinsics
in for now, but they can be removed if there is not noticable performance benefit anymore.

4. The inlining heuristics are tweaked in a way that enables more aggressive inlining
of recognized methods: +1 level of inlining depths, call sites of recognized methods are
not counted in the inlining heuristic.

The constant pool pointer must be restored before any parallel
moves at the catch-entry block.

In addition, this CL removes CatchEntryInstr and folds its
functionality into CatchBlockEntryInstr. Until now every catch-block
started with CatchBlockEntryInstr followed by a CatchEntryInstr.

This simplifies a lot of code in the compiler and avoids issues
with allocator-move code inserted between the two instructions.

fschneider@google.com ee0aaf0453 Enable allocation sinking for non-implicit closures.
In optimized code we can eliminate the allocation of closures that are not
escaping and where all calls are inlined.

Closures are currently allocated with a special IL instruction (CreateClosure).
This CL changes this for non-implicit closures and allocates them
like normal objects. The fields for the function and the context are
initialized like instance fields. This way object allocation sinking can
handle closures like any other objects.

This CL removes the remaining missing cases when inlining closure

In order to benefit for code using forEach, I added GrowableObjectArray.forEach
to the functions that should always be inlined.

I also renamed BuildLoadContext/BuildStoreContext helpers in the flow
graph builder to better match what they do.

Fix a bug in relational operations in 64 bit mode: if ICData specifies double and Smi as possible arguments, we generate code for double and unbox or convert to double the inputs. These works only if smi can fit into the double. Current solution for 64-bit architecture is to disallow two smi-s as input to a polymorphic comparison instruction (equality, relational).

srdjan@google.com b9b689d20a Split LoadStatic into two instructions: load static field, load value from static field. This allows to canonicalize loads, thus reducing the number of inlined constants. Has large benefit on x64 (DeltaBlue). Note different register allocation spec for ia32, otherwise large regression in DeltaBlue is introduced.

kmillikin@google.com 0b39927d30 Initial implementation of on-stack replacement (OSR).
Add profiling support to select OSR candidates and launch the compiler
for OSR, followed by entry to the function at the OSR entry point.

Implemented only on IA32 and X64.  The initial implementation can be
improved in various ways --- specifically: tuning of profiling
parameters and incorporation of feedback about the actual values seen
at OSR entry.

fschneider@google.com 9c386a80df Improve array bounds check elimination for growable lists.
Previously we could not eliminate bounds checks for
growable lists, even though the length is not modified.

This CL removes obsolete restrictions and enables elimination
of checks as long as the length does not change.

This restriction were there originally because the CheckArrayBounds
instruction loaded the length from the array itself. Now, the length-load
and the  actual check are split into separate instructions.
Tracking side-effects for normal loads determines can now determine if
the length-load is invariant.

fschneider@google.com 9a6657cd4d Eliminate temporary locals for some expressions
This CL affects a subset of expressions that use temporary locals: constructor
calls, array literals and and instance getter postfix-ops.

For expressions that are de-sugared in the parser I added LetNode.
It creates a scoped temporary local bound to an initializing expression.

For expressions where we need a temporary local at graph-building time,
I added a helper class TempLocalScope to easily create a single temporary
local in the graph builder since this is a frequently recurring pattern.

This simplifies code in the parser and the graph builder and also fixes a
bug with indexed-super invocation and NoSuchMethod.

The compiler turns equality checks with null into
strict equal comparisons. Make the compiler backend
create a pc descriptor for the runtime call so that
the debugger can break on x == null and x != null.
