Re-land: Use map transitions when defining accessor properties.

This is basically r11496, with the following changes:

* Set back pointers in maps (cherry-picked from r11528)

* Fixed size calculation in CopyInsert, as proposed by mstarzinger/rossberg

* DefineFastAccessor uses GetCallbackObject instead of GetValue (for __proto__)

* Put the code under a new flag, which is disabled by default

* Cut down the corresponding regression test

* Adapted bootup memory test, we actually only need a bit more memory on 64bit without snapshots, which can easily explained by more live maps lying around. Note that the snapshot variants are back to their previous limits.

Next steps: Investigate any performance degradationswith the flag enabled, and finally remove the flag when things are OK. Furthermore, GetCallbackObject should be merged into GetValue, the distinction is confusing and error-prone.

MIPS: Array index computation dehoisting.

Port r11596 (0cee9fca)

Original commit message:
Array index computation dehoisting.

When an array index (in an array access) is a simple "expression + constant", just embed the constant in the array access operation so that the full index expression is (potentially) no longer used and its live range can be much shorter.
This is effective in conjunction with array bounds check removal (otherwise the index is anyway used in the check).

their compilers support '-m32' option individually. If yes,
then add this option into cflags and ldflags. The exception is

Array index computation dehoisting.

When an array index (in an array access) is a simple "expression + constant", just embed the constant in the array access operation so that the full index expression is (potentially) no longer used and its live range can be much shorter.
This is effective in conjunction with array bounds check removal (otherwise the index is anyway used in the check).

Declare more functions returing a MaybeObject* with MUST_USE_RESULT.

No violations found this time.

Additionally I changed one function JSDate::GetField that never returns
a failure to return a Object* instead.

Split nodes and edges into separate arrays in heap profiler.

This allowed the following changes:
  - heap profiler now makes one pass less over the heap.
  - HeapEntriesMap does not allocate EntryInfo per each entry.
  - there's no need for an extra pass to set indexes before serialization.

As a result snapshot taking time has reduced up to 2x times.

Make Error.prototype.name writable again, as required by the spec and the web.

Address http://code.google.com/p/chromium/issues/detail?id=69187 by instead
ignoring getters on ReferenceError.prototype.name in Error.prototype.toString.

And while we're at it, do the same for SyntaxError and TypeError, and the
properties "message", "type", and "arguments" on all of them, which
potentially have similar issues.

Implement explicit back pointers in transition tree.

This makes back pointers in the map transition tree explicit by having
accurate back pointers throughout the lifetime of maps instead of
establishing and destroying back pointers before and after each marking
phase. This is a prerequisite for being able to clear map transitions
during incremental marking.

Make DeltaBlue performance more stable by ignoring type feedback that
tells us that a map can transition to another map when we are generating
code for load operations. This may cause us to deopt if the same routine
is seeing different maps caused by branching in constructors. If so, I
have a different change that is around 100 times more complicated that
lets us generated Crankshaft code for negative lookups.
