25 (struct store_immediate_info): Add bitregion_start and bitregion_end
27 (store_immediate_info::store_immediate_info): Add brs and bre
28 arguments and initialize bitregion_{start,end} from those.
29 (struct merged_store_group): Add bitregion_start, bitregion_end,
30 align_base and mask fields. Drop unnecessary struct keyword from
31 struct store_immediate_info. Add do_merge method.
32 (clear_bit_region_be): Use memset instead of loop storing zeros.
33 (merged_store_group::do_merge): New method.
34 (merged_store_group::merge_into): Use do_merge. Allow gaps in between
35 stores as long as the surrounding bitregions have no gaps.
36 (merged_store_group::merge_overlapping): Use do_merge.
37 (merged_store_group::apply_stores): Test that bitregion_{start,end}
38 is byte aligned, rather than requiring that start and width are
39 byte aligned. Drop unnecessary struct keyword from
40 struct store_immediate_info. Allocate and populate also mask array.
41 Make start of the arrays relative to bitregion_start rather than
42 start and size them according to bitregion_{end,start} difference.
43 (struct imm_store_chain_info): Drop unnecessary struct keyword from
44 struct store_immediate_info.
45 (pass_store_merging::gate): Punt if BITS_PER_UNIT or CHAR_BIT is not 8.

52 (split_store::split_store): Initialize orig to false.
53 (find_constituent_stmts): Return store_immediate_info *, non-NULL
54 if there is exactly a single original stmt. Change stmts argument
55 to pointer from reference, if NULL, don't push anything to it. Add
56 first argument, use it to optimize skipping over orig stmts that
57 are known to be before bitpos already. Simplify.
58 (split_group): Return unsigned int count how many stores are or
59 would be needed rather than a bool. Add allow_unaligned argument.
60 Change split_stores argument from reference to pointer, if NULL,
61 only do a dry run computing how many stores would be produced.
62 Rewritten algorithm to use both alignment and misalign if
63 !allow_unaligned and handle bitfield stores with gaps.
64 (imm_store_chain_info::output_merged_store): Set start_byte_pos
65 from bitregion_start instead of start. Compute allow_unaligned
66 here, if true, do 2 split_group dry runs to compute which one
67 produces fewer stores and prefer aligned if equal. Punt if
68 new count is bigger or equal than original before emitting any
69 statements, rather than during that. Remove no longer needed
70 new_ssa_names tracking. Replace num_stmts with
71 split_stores.length (). Use 32-bit stack allocated entries
72 in split_stores auto_vec. Try to reuse original store lhs/rhs1
73 if possible. Handle bitfields with gaps.
74 (pass_store_merging::execute): Ignore bitsize == 0 stores.
75 Compute bitregion_{start,end} for the stores and construct
76 store_immediate_info with that. Formatting fixes.

27183 function) to match all of the P9V_BUILTIN_VEC_VCMNE_P entries
