* builtins.c (get_object_alignment_1): Return whether we can determine
the alignment or conservatively assume byte alignment. Return the
alignment by reference. Use get_pointer_alignment_1 for dereference
alignment.
(get_pointer_alignment_1): Return whether we can determine the
alignment or conservatively assume byte alignment. Return the
alignment by reference. Use get_ptr_info_alignment to get SSA name
alignment.
(get_object_alignment): Update call to get_object_alignment_1.
(get_object_or_type_alignment): Likewise, fall back to type alignment
only when it returned false.
(get_pointer_alignment): Update call to get_pointer_alignment_1.
* fold-const.c (get_pointer_modulus_and_residue): Update call to
get_object_alignment_1.
* ipa-prop.c (ipa_modify_call_arguments): Update call to
get_pointer_alignment_1.
* tree-sra.c (build_ref_for_offset): Likewise, fall back to the type
of MEM_REF or TARGET_MEM_REF only when it returns false.
* tree-ssa-ccp.c (get_value_from_alignment): Update call to
get_object_alignment_1.
(ccp_finalize): Use set_ptr_info_alignment.
* tree.h (get_object_alignment_1): Update declaration.
(get_pointer_alignment_1): Likewise.
* gimple-pretty-print.c (dump_gimple_phi): Use get_ptr_info_alignment.
(dump_gimple_stmt): Likewise.
* tree-flow.h (ptr_info_def): Updated comments of fields align and
misalign.
(get_ptr_info_alignment): Declared.
(mark_ptr_info_alignment_unknown): Likewise.
(set_ptr_info_alignment): Likewise.
(adjust_ptr_info_misalignment): Likewise.
* tree-ssa-address.c (copy_ref_info): Use new access functions to get
and set alignment of SSA names.
* tree-ssa-loop-ivopts.c (rewrite_use_nonlinear_expr): Call
mark_ptr_info_alignment_unknown.
* tree-ssanames.c (get_ptr_info_alignment): New function.
(mark_ptr_info_alignment_unknown): Likewise.
(set_ptr_info_alignment): Likewise.
(adjust_ptr_info_misalignment): Likewise.
(get_ptr_info): Call mark_ptr_info_alignment_unknown.
* tree-vect-data-refs.c (vect_create_addr_base_for_vector_ref):
Likewise.
(bump_vector_ptr): Likewise.
* tree-vect-stmts.c (create_array_ref): Use set_ptr_info_alignment.
(vectorizable_store): Likewise.
(vectorizable_load): Likewise.
