[asan-asm-instrumentation] Fixed asan-asm-stacktrace-test.cc

[ygorshenin]

Summary

Fixed asan-asm-stacktrace-test.cc. Now it's supported on x86_64 and added test run when no debug info is generated.

[ygorshenin]

PTAL

[eugenis]

You could check that the first two lines (READ and "in foo") are still present even w/o unwind tables.

[ygorshenin]

Fixes.

[ygorshenin]

Done, thanks!
