Improved performance of garbage collection by moving the function that updates pointers during compacting collection into the updating visitor. This gives the compiler a better chance to inline and avoid a function call per (potential) pointer.

Extended the shell sample with a --runtime-flags option.

Added Visual Studio project files for the shell.cc and process.cc samples.

If V8 without snapshot if preferred only v8_base.vcproj and v8.vcproj are
required and a project which uses V8 should depend on v8.vcproj.
Two sample project files are available as well. These are v8_shell_sample.vcproj
for building the sample in samples\shell.cc and v8_process_sample.vcproj for
building the sample in samples\process.cc. Add either of these (or both) to a
solution with v8_base, v8, v8_mksnapshot and v8_snapshot set up as described
above and have them depend on v8_snapshot.
Python requirements
-------------------
When using the Microsoft Visual Studio project files Python version 2.4 or later
