mrg 8fdd01b3ee fixes for GCC 6:
- -Wstrict-prototypes is not available for C++, so don't try to
  ignore it for C++.
- remove many _DIAGASSERT() checks against not NULL for functions
  with arguments with nonnull attributes.  in two cases, leave
  code behind that should set defaults to "(null)".
- use -Wno-error=frame-address for i386 mcount, as it seems valid
  to assume the caller will have a frame.fair
