removing duplicate adjacent entries having the same line number, and 2) using
special opcodes to encode multiple machine register state changes in one byte.
Also made a fix involving the order in which static initializers are performed.

   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.

Support building with or without unaligned accesses by using scons flag simulatorunalignedaccesses.

$ scons simulator=arm simulatorunalignedaccesses=off
$ scons simulator=arm simulatorunalignedaccesses=on

If simulatorunalignedaccesses is not specified (or specified as default) the default is to use unaligned accesses.

This is to make possible enabling usage of the new profiling subsystem
in Chromium without much hassle. The idea is pretty simple: unless the
new profiling API is used, all works as usual, as soon as Chromium
starts to use the new API, it will work too.

Remove messages.h from v8.h and include it explicitly in only the few places
it is needed.  Many files relied on getting handles-inl.h implicitly from
messages.h through v8.h, so include handles-inl.h explicitly in v8.h
instead.

Remove zone-inl.h from header files where it is not needed, can be replaced
by a forward declaration, or can be replaced by zone.h (specifically,
factory.h and heap.h).  Include zone.h or zone-inl.h in header files where
it was implicitly included via heap.h or factory.h.  Prefer zone.h over
zone-inl.h in header files where possible by including zone-inl.h in .cc
files.

It is now possible to experiment with profiler guided optimizations when building V8. First build an instrumented sample shell:

  > scons pgo=instrument sample=shell

Then run the JavaScript code to optimize for using that sample shell. Finally build an optimized sample shell.

  > scons pgo=optimize sample=shell

Currently this does not work when building V8 as a DLL due to scons deleting v8.exp prior to the pgo=optimize step.

Due to a bug in Visual Studio (seen in version 2008) the function MessageDispatchHelperThread::Run() in debug.cc needs to be empty for this to work.
