From-SVN: r193443

This patch defines a new asan_shadow_offset target macro, instead of
having a mere macro in the asan.c file. It becomes thus cleaner to
define the target macro for targets that supports asan, namely x86 for
now. The ASAN_SHADOW_SHIFT (which, along with the asan_shadow_offset
constant, is used to compute the address of the shadow memory byte for
a given memory address) is defined in asan.h.

-faddress-sanitizer if not supported by target.

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.
