	* config/rs6000/aix.h (OS_MISSING_POWERPC64): Define.
	(OS_MISSING_ALTIVEC): Define.
	* config/rs6000/darwin.h (ASM_SPEC): Be generous about supplying
	-force_cpusubtype_ALL.
	* config/rs6000/rs6000.c (rs6000_override_options): Rearrange
	CPU information table; now always set all CPU-specific values.
	Also, use Altivec and powerpc64 when chip and OS supports them.
