[compiler-rt] r209282 - [asan] Fix x86 asm instrumentation to preserve flags.

[Evgeniy Stepanov]

Yeah, this is really bad.
There are further issues: even if this flag is fixed, we would still
try to build and run asan_test for x86_64 and i686, because host gcc
supports those.

I've filed http://llvm.org/bugs/show_bug.cgi?id=20490 and sent
http://reviews.llvm.org/D4718.
