63defee477 First implementation of allocation elimination in Hydrogen. 
This change implements a simple data-flow analysis pass over captured
objects to the existing escape analysis. It tracks the state of values
in the Hydrogen graph through CapturedObject marker instructions that
are used to construct an appropriate translation for the deoptimizer to
be able to materialize these objects again.

This can be considered a combination of scalar replacement of loads and
stores on captured objects and sinking of unused allocations.

d2c443b774 Extract hardcoded error strings into a single place and replace them with enum. 
I'd like to propagate bailout reason to cpu profiler.
So I need to save it into heap object SharedFunctionInfo.
But:
1) all bailout reason strings spread across all the sources.
2) they are native strings and if I convert them into String then I may have a performance issue.
3) one byte is enough for 184 bailout reasons. Otherwise we need 8 bytes for the pointer.

Also I think it would be nice to have error strings collected in one place.
In that case we will get additional benefits:

It allows us to keep this set of messages under control.
It gives us a chance to internationalize them.
It slightly reduces the binary footprint.

From the other hand the developers have to add new strings into that enum.

e9cc78af7e Fix for V8 issue 2795: Check fails with deopt for mjsunit/array-store-and-grow 
(https://code.google.com/p/v8/issues/detail?id=2795)

The reason is when allocating and building arrays in hydrogen we need to ensure
we do any int32-to-smi conversions BEFORE the allocation. These conversions can
at least theoretically deoptimize. If this happens before all the fields of the
newly allocated object are filled in, we will have a corrupted heap.

3cdeb2f9cd Avoid adding HWrapReceiver during graph building. 
This adds an early check to the graph builder which prevents adding an
HWrapReceiver instruction if the receiver type is already known at graph
building time. Also HAllocate no longer unnecessarily postpones setting
it's type until type inference but sets it right away. These changes are
in preparation for escape analysis.

b8d7bee4a3 Avoid tagged values for Instructions that truncate the operands with ToNumber. 
I case the ToNumber is applied to a non numeric value but its not observable (some constants and oddballs) we should already do it in hydrogen...

44f576ba65 Replace BuildExternalArrayElementAccess() with AddExternalArrayElementAccess(). 
This is trivial cleanup. All calls to BuildExternalArrayElementAccess()
pass the result to AddInstruction().

ec8c6f4692 Rename AllocationSiteInfo to AllocationMemento 
This is just a rename change with the exception of a bug found along the way in
CodeStubGraphBuilder<FastCloneShallowArrayStub>::BuildCodeStub(). There, the
intent is to get the boilerplate object from an AllocationSite. But the wrong
HObjectAccess was used. It only succeeds because it happened to be the same
offset :).

d750a6dcd8 Consistently use HStringAdd instead of HCallStub with CodeStub::StringAdd. 
Previously there were two ways to actually use the StringAddStub
from Hydrogen:

- Either using HStringAdd (which implied NO_STRING_CHECK_IN_STUB
  and and does the argument handling internally),
- or using HCallStub with CodeStub::StringAdd (which implied
  NO_STRING_ADD_FLAGS and expected the arguments to be on the
  stack already).
