Clean up a few -faddress-sanitizer stragglers.

 // Fake Address Sanitizer run-time support.
 // Enough for programs to link and run, but will not find any errors.
 // Also, linking this to shared libraries voids the warranty.
 //
 // We need this fake thunks if we build Chrome with ASAN support because
 // pyautolib DSO is instrumented with ASAN and is loaded to regular python
 // process that has no ASAN runtime.
 //
 // We have three options here:
 // 1) use our custom build of Python that have ASAN runtime linked in,
 // 2) do not instrument pyautolib with ASAN support,
 // 3) use this fake asan thunks linked to pyautolib so that instrumented code
 //    does not complain.
 //
 // Note that we should not use real ASAN runtime linked with DSO because it will
 // not have information about memory allocations made prior to DSO load.
 //
 // Option (2) is not easy because pyautolib uses code from Chrome
 // (see chrome_tests.gypi, dependencies for target_name: pyautolib) that
-// has been instrumented with ASAN. So even if we disable -faddress-sanitizer
+// has been instrumented with ASAN. So even if we disable -sanitize=address
 // for pyautolib own sources, ASAN instrumentation will creep in from there.
 // To avoid ASAN instrumentation, we might force Chrome build to compile all our
-// dependencies one more time without -faddress-sanitizer.
+// dependencies one more time without -fsanitize=address.
 //
 // Note also that using these empty stubs prevents ASAN from catching bugs in
 // Python-pyautolib process. But we do not need it, we are interested in Chrome
 // bugs.
