rs6000: Remove ALTIVEC_BUILTIN_MASK_FOR_STORE

It turns out that the target hook that this is supposed to satisfy
disappeared in 2004.  Probably time to retire it.

gcc/
	* config/rs6000/rs6000-builtin.def (MASK_FOR_STORE): Remove.
	* config/rs6000/rs6000-call.c (rs6000_expand_builtin): Remove
	all logic for ALTIVEC_BUILTIN_MASK_FOR_STORE.
