5649 arguments and initialize bitregion_{start,end} from those.
5650 (struct merged_store_group): Add bitregion_start, bitregion_end,
5651 align_base and mask fields. Drop unnecessary struct keyword from
5652 struct store_immediate_info. Add do_merge method.

5654 (merged_store_group::do_merge): New method.

5658 (merged_store_group::apply_stores): Test that bitregion_{start,end}
5659 is byte aligned, rather than requiring that start and width are
5660 byte aligned. Drop unnecessary struct keyword from
5661 struct store_immediate_info. Allocate and populate also mask array.
5662 Make start of the arrays relative to bitregion_start rather than
5663 start and size them according to bitregion_{end,start} difference.

5676 to pointer from reference, if NULL, don't push anything to it. Add
5677 first argument, use it to optimize skipping over orig stmts that
5678 are known to be before bitpos already. Simplify.
5679 (split_group): Return unsigned int count how many stores are or
5680 would be needed rather than a bool. Add allow_unaligned argument.
5681 Change split_stores argument from reference to pointer, if NULL,
5682 only do a dry run computing how many stores would be produced.
5683 Rewritten algorithm to use both alignment and misalign if
5684 !allow_unaligned and handle bitfield stores with gaps.
5685 (imm_store_chain_info::output_merged_store): Set start_byte_pos
5686 from bitregion_start instead of start. Compute allow_unaligned
5687 here, if true, do 2 split_group dry runs to compute which one
5688 produces fewer stores and prefer aligned if equal. Punt if
5689 new count is bigger or equal than original before emitting any
5690 statements, rather than during that. Remove no longer needed
5691 new_ssa_names tracking. Replace num_stmts with
5692 split_stores.length (). Use 32-bit stack allocated entries
5693 in split_stores auto_vec. Try to reuse original store lhs/rhs1
5694 if possible. Handle bitfields with gaps.
5695 (pass_store_merging::execute): Ignore bitsize == 0 stores.
