Add source map support to tick processor.
...
Added a console parameter for source map to the tick processor.
The tickprocesspor reads in the source maps and uses it to output the original filename, line number and column in the profile.
Modified d8 to output column numbers into the log, since this is needed to do source mapping.

Add --trace-hydrogen-filter flag.
...
The flag restricts hydrogen.cfg output to functions passing the filter,
similar to what --hydrogen-filter does for optimization in general.
This is useful for investigating large repro cases where tracing all
functions would lead to an impractically large hydrogen.cfg file, but
restricting optimization using --hydrogen-filter is undesirable
(e.g. because it might cause the issue to no longer reproduce).

Temporarily disable optimization for StringWrappers to use native valueOf
...
V8 stores this information directly in the map of the wrapper, however,
it is not invalidated when the prototype of the wrapper is changed, so
once the bit is set, it is no longer possible to override valueOf.
This bug is currently hidden in Chrome since the i18n extension always
modifies the String.prototype, and so the optimization never kicks in.
Disabling the optimization temporarily allows for snapshotting i18n now.

Fix crash due RegExpAtom method called on RegExpCharacterClass object.

In the RegExpUnparser::VisitText(RegExpText* that, void* data) function always RegExpUnparser::VisitAtom function called via that->elements()->at(i).data.u_atom->Accept(this, data); even if the type of the object is RegExpCharacterClass.
The problem shows using g++ 4.7(.2, .3) since r16232, since GCC optimizes virtual method calls to direct calls based on __final/final hints. Tested on MIPS and x64:
Program received signal SIGSEGV, Segmentation fault.
0x0000000000588928 in v8::internal::RegExpUnparser::VisitAtom(v8::internal::RegExpAtom*, void*) ()
This cleans up the TextElement class to avoid the unsafe+unchecked union access, that caused the crash.

Promote ArrayBuffer, DataView and typed arrays to non-experimental.
...
The primary reason for this change is to bake these guys into the
snapshot.
Flag definitions (--harmony-typed-arrays, --harmony-array-buffer) are
still there so that Blink does not complain, but they are noop and
default to true.

Replace OS::MemCopy with memcpy in typed array initialization.
...
This is an attempt to fix a weird perf regression on MacOS X 10.6 bot.
Perf regression is not reproducible on MacOS X 10.8.
This difference in memory-copying routines is the only reasonable
difference in the algorithm. We should try and see.
