Log message:
	* tree-dfa.c (may_alias_p): If VAR and PTR are pointers with the
	same alias set, return false.
	(get_memory_tag_for): Group based on alias set classes, not on
	conflicting alias sets.
	* tree-must-alias.c (promote_var): Don't bring aliases over when
	all the may-aliases of a non-promotable variable are promoted.
