re PR tree-optimization/68786 (Aligned masked store is generated for unaligned pointer)
PR tree-optimization/68786
* tree-if-conv.c: Include builtins.h.
(predicate_mem_writes): Put result of get_object_alignment (ref)
into second argument's value.
* tree-vect-stmts.c (vectorizable_mask_load_store): Put minimum
pointer alignment into second argument's value.
* tree-data-ref.c (get_references_in_stmt): Use value of second
argument for build_aligned_type, and only the type to build
a zero second argument for MEM_REF.
* internal-fn.c (expand_mask_load_optab_fn,
expand_mask_store_optab_fn): Likewise.
