05507cc3ea Reland II of 'Optimize trivial regexp disjunctions' CL 1176453002 
This change rewrites regexps like (ab|ac|z|ad|ae|af) into (a[b-f]|z).  We can only reorder disjunctions like this for case-dependent regexps.  For case-independent regexps, the disjunctions should be pre-sorted for best results.

aeb09e6dcf Merge v8_optimized_debug 1 and 2 
All builders that used level 1 should meanwhile define
v8_enable_slow_dchecks, and so they can use level 2 without losing
coverage. Level 2, however, is considerably faster, so we want to use it
on those builders as well. The make optdebug setting is not affected by
this change.

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.

This change will ensure that all non-optimized code will be compiled
with debug break slots when debugging is initiated. This is handled by
scanning the heap for non-optimized functions without debug break slots and setting their code to be lazy recomplied. When the lazy recompilation happens the code will ge generated with debug break slots (if debugging is still active at that point in time).

123500999f Reland 7917: 
Better support for 'polymorphic' JS and external arrays

Allow  keyed store/load stubs to switch between external array and fast JS arrays without forcing a state transition to the generic stub.

There CL consists of two pieces of functionality. First, code stubs for fast element arrays don't immediately transition to the MEGAMORPHIC state when there's a map mismatch. Second, two ICs are cached per map for fast elements, the MONOMORPHIC version, and a new MEGAMORPHIC version that handles two or more different maps and dispatches to shared stubs to perform the array operation.

This is for mobile platforms where application footprint size is
important. To avoid including compression libraries into V8, we assume
that the host machine have them (true for Linux), and rely on embedder
to provide decompressed data.

Currently, only snapshot data can be comressed. It is also possible to
compress libraries sources, but it is more involved and will be

af7b6fecfe Split globals.h into two parts, where only one depends on V8. 
Made allocation.{h,cc} independent of V8, allowing utils.h to allocate
vectors and collectors.

9c503a8330 Fix some inconsistent formatting. 
I noticed we sometimes had extra spaces before and after the "const"
keyword.  Probably the result of a search and replace gone wrong.

This is a whitespace only change.

1695003bb9 Heap profiler: reduce heap snapshots size. 
The size of a snapshot is now 65-80% of the JS heap size (tested on
GMail and Wave), previously it was >200%.

d53f05e3e2 Fix warnings on Win64. 
Set warning level to /W3 and change implicit conversions from size_t
to int. Most "fixes" are simply manifesting the implicit casts or using
a special strlen replacement that returns int.

fb2317b63b New snapshot framework. Doesn't work on ARM yet (code targets 
are different).  Is able to deserialize the whole heap and run
some stuff.  Not available as the primary snapshot system yet.
