47e03a0000 fix -Wunused-but-set-variable for gcc-4.6 on x64
* src/third_party/valgrind/valgrind.h: Update from upstream valgrind
  r11899, so as to get around some unused value warnings.  Also adds
  support for darwin.

  This version of valgrind.h differs from the original in that all
  instances of "unsigned long long int" have been replaced with
  "uint64_t", as the former is not allowed in ISO C++ 89.

  See https://bugs.kde.org/show_bug.cgi?id=211926 for the upstream bug
  report.

ec58c05f4e Add support for startup data (snapshot) compression.
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
addressed in another CL.

00bc2db28f ARM: Support hardfloat in SCons build and make it a build time setting
Add option armeabi to the SCons build for selecting the floating point variant to use. Also add externally defined CCFLAGS environment for all targets. Run test.py with option -S armeabi=hardfloat to test with hardfloat enabled.

Make selecting hardfloat EABI variant a build-time option instead of a runtime option.

Add a simple check of the EABI variant during V8 initialization to exit if the compilation was not configured correctly. The reason for this is that GCC does not provide a compile time symbol defining the EABI variant. This check is not fool-proof as it cannot check the compilation configuration used for the snapshot if any.

3003b2156b Basic GDB JIT Interface integration.
It has certain overheads even when gdb is not attached so it is guarded by ENABLE_GDBJIT_INTERFACE define and --gdbjit flag.

e21d76a0e3 1. Added support for object printing for release mode using the
objectprint=on (defaults to off) option (which defines OBJECT_PRINT).
2. Added the ability to print objects to a specified file instead of
   just stdout.
3. Added a use_verbose_printer flag (true by default) to allow some
   object printouts to be less verbose when the flag is false.
4. Fixed a bug in VSNPrintF() where it can potentially write into an
   empty char vector.
