Based on a patch submitted by Jens Alfke:

Tag Mac OS X VM regions allocated by V8. This has no effect other than making
it possible to identify V8 allocations in the vmmap(1) memory profiling tool,
to get a better idea of an embedder's/Chrome's memory usage.
CRBUG=23455
TEST=Tested by running vmmap(1) and looking for "Memory tag=255" in the output.
