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.

We already reject flags that don't have the CC1Option flag,
but we would previously do so after parsing the command-line
arguments.
Since the option parser now has a parameter for excluding options,
we should just use that instead.
