This revision is now accepted and ready to land.

The patch looks sensible, but isn't actually exercised: I ran a `sparcv9-sun-solaris2.11` build with it included, which made no difference.  However, on closer inspection, the `sanitizer_coverage_trace_pc_guard*.cpp` tests didn't run: they aren't supported together with ubsan, while asan isn't supported on SPARC due to a `clang` bug/limitation.

That said, the patch is plausible, so LGTM.
