Options

aix.h (OS_MISSING_POWERPC64): Define. 

	* 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.

@option{-mpower}, @option{-mpower2}, @option{-mpowerpc64},
@option{-mpowerpc-gpopt}, @option{-mpowerpc-gfxopt},
@option{-mstring}. The particular options set for any particular CPU
will vary between compiler versions, depending on what setting seems
to produce optimal code for that CPU; it doesn't necessarily reflect
the actual hardware's capabilities. If you wish to set an individual
option to a particular value, you may specify it after the
@option{-mcpu} option, like @samp{-mcpu=970 -mno-altivec}.
On AIX, the @option{-maltivec} and @option{-mpowerpc64} options are
not enabled or disabled by the @option{-mcpu} option at present, since
AIX does not have full support for these options. You may still
enable or disable them individually if you're sure it'll work in your
environment.
