29702bfe5f Re-land 242726 to use RAII to do cleanup 
The LooksLikeCodeInBug11395() codepath was returning without clearing
the ProcessedAllocas cache.

d30055fb9f Don't try to instrument allocas used by outlined SEH funclets 
Summary:
Arguments to llvm.localescape must be static allocas. They must be at
some statically known offset from the frame or stack pointer so that
other functions can access them with localrecover.

If we ever want to instrument these, we can use more indirection to
recover the addresses of these local variables. We can do it during
clang irgen or with the asan module pass.
