Authentication-results: sourceware.org; auth=none

Hi all,

Here's a patch for optional Asan instrumentation of inline assembly.

This version scans gimple for GIMPLE_ASMs and performs usual instrumentation
of arguments with memory constraints ("m", "o", etc.) with fixed size.

Instrumentation is turned off by default.

This was successfully bootstrapped and regtested on x64. I have also
instrumented and ran ffmpeg regression testsuite (it seems to have quite
some inline asm).
