Initial import of asan from the Google branch
This patch imports the initial state of asan as it was in the
Google branch.
It provides basic infrastructure for asan to instrument memory
accesses on the heap, at -O3. Note that it supports neither stack nor
global variable protection.
The rest of the patches of the set is intended to further improve this
base.
