Original commit message:
* New atomic code stubs for x64, ia32, arm, arm64
* Add convenience functions JumpIfNotValidSmiValue, JumpIfUintNotValidSmiValue
to macro-assembler-ia32 (API based on x64 macro assembler)
* Remove runtime implementation of Atomics.load, the code stub should always be
called instead
* Add new test to mjsunit atomics test; check that Smi values of different
sizes are supported when possible, else fall back to HeapNumbers
These changes were needed to add another codestub:
* Bump kStubMajorKeyBits from 7 to 8
* Reduce ScriptContextFieldStub::kSlotIndexBits from 13 to 12

* Minor cleanup to ExecuteInstruction() to remove an unncessary
'processed' variable.

Fixes for misnamed toolchain from https://github.com/appcelerator/v8_titanium.
Added a way to specify the NDK path since the Mac versions of the NDK aren't checked into the tools repo.
Disabled a few dependencies which do not build on the Mac but which aren't needed for building usable V8 static libraries.
Made the including of libdl and librt omitted for Mac hosted builds.

This change implements switch as a balanced if/else tree or break table or
hybrid. A lot of asm.js modules are expected to extensively use switch
alongside function tables that can benefit from a better implementation.

Despite man page documentation:
-f Display the symbol table of a dynamic library flat (as one
file not separate modules).
`nm` on mac treats `-f` as a shorthand for `-format`. The `-f` argument
does not seem to be required, so just remove it completely.
(For `-format` documentation - see `nm --help` on mac).

Check if a previous run left an inconsistent state behind.
The check is right before trying to push a new state as then
all information is available, like commit message and tag
name.
This is still only a band-aid. If gnumbd is down for a
longer period, an unprocessed commit won't be found, but
the push attempt will still fail.

This patch replaces the unused 'take_snapshot' parameter on FatalProcessOutOfMemory()
with a 'is_heap_oom' parameter. The parameter is set to true on error paths where the
JS heap is out of memory, as distinct from a malloc() failure i.e. process out of memory.
The message output to stderr or passed to embedding applications via FatalErrorCallback
is 'Javascript heap out of memory' rather than 'process out of memory'.

The usage of __attribute__((format(x, y)) was either wrong or missing from multiple functions, leading to erroneous formats. This CL:
- Imports PRINTF_FORMAT macro from Chrome's src/base/compiler-specific.h.
- Uses it appropriately.
- Imports Chrome's base/format_macros.h mainly to fix size_t formats (further cleanup could be done).
- Fixes a bunch of incorrect formats.
