poly_int: store merging
This patch makes pass_store_merging track polynomial sizes
and offsets. store_immediate_info remains restricted to stores
with a constant offset and size.

gcc/
* poly-int-types.h (round_down_to_byte_boundary): New macro.
(round_up_to_byte_boundary): Likewise.
* expr.h (get_bit_range): Add temporary shim.
* gimple-ssa-store-merging.c (store_operand_info): Change the
bitsize, bitpos, bitregion_start and bitregion_end fields from
unsigned HOST_WIDE_INT to poly_uint64.
(merged_store_group): Likewise load_align_base.
(compatible_load_p, compatible_load_p): Update accordingly.
(imm_store_chain_info::coalesce_immediate_stores): Likewise.
(split_group, imm_store_chain_info::output_merged_store): Likewise.
(mem_valid_for_store_merging): Return the bitsize, bitpos,
bitregion_start and bitregion_end as poly_uint64s rather than
unsigned HOST_WIDE_INTs. Track polynomial offsets internally.
(handled_load): Take the bitsize, bitpos,
bitregion_start and bitregion_end as poly_uint64s rather than
unsigned HOST_WIDE_INTs.
(pass_store_merging::process_store): Update call to
mem_valid_for_store_merging.
