Remove the -faltivec alias option and replace it with -maltivec everywhere. The alias was only ever used on darwin and had some issues there, and isn't used in practice much. Also fixes a problem with -mno-altivec not turning off -maltivec. Also add a diagnostic for faltivec/fno-altivec that directs users to use maltivec options and include the altivec.h file explicitly. llvm-svn: 298449
