This revision is now accepted and ready to land.

In this new patch:

- Add support for __builtin_bzero (-Wsuspicious-bzero), improve diagnostics for platforms that define bzero to __builtin_memset
- Suppress the diagnostic when the `0` in memset(ptr, something, 0) came from a macro expansion.
- Address review comments

Thanks!
