Major changes to the Chrome allocator.
Changes include:
* Fix tcmalloc to release memory. Implements the TCMalloc_SystemCommit()
mechanism so that tcmalloc can implement SystemRelease() and later
reuse that memory.
* Enable dynamic switching of allocators based on an environment variable.
Users can now switch between tcmalloc, jemalloc, the default windows
heap, and the windows low-fragmentation heap.
* Implements set_new_mode() across all allocators so that we can be sure
that out-of-memory conditions are handled safely.
BUG=18345
TEST=none; plan to get all unit tests running through these allocators.
