This appears to be present in compiler-rt upstream, but as part
of more intrusive changes.  For gcc, the lack of this results in
a fatal warning (-Werror) at build-time.

libsanitizer:

	* sanitizer_common/sanitizer_atomic_clang_other.h [_MIPS_SIM
	&& _MIPS_SIM == _ABIO32] (lock): Add initializer for .pad member.
