Note that GCC doesn't perform any ASAN optimizations yet (if the same address

is written or read several times in the same bb, it doesn't optimize away the

tests).  We plan to first switch to first expanding the shadow memory checks as

simple builtins without control flow, performing optimizations on them and only

later on (in fab pass?) to expand it to the longer sequences with control flow

in them.
