8091 is byte aligned, rather than requiring that start and width are
8092 byte aligned. Drop unnecessary struct keyword from
8093 struct store_immediate_info. Allocate and populate also mask array.

8110 are known to be before bitpos already. Simplify.
8111 (split_group): Return unsigned int count how many stores are or
8112 would be needed rather than a bool. Add allow_unaligned argument.
8113 Change split_stores argument from reference to pointer, if NULL,
8114 only do a dry run computing how many stores would be produced.
8115 Rewritten algorithm to use both alignment and misalign if
8116 !allow_unaligned and handle bitfield stores with gaps.
8117 (imm_store_chain_info::output_merged_store): Set start_byte_pos
8118 from bitregion_start instead of start. Compute allow_unaligned
8119 here, if true, do 2 split_group dry runs to compute which one
8120 produces fewer stores and prefer aligned if equal. Punt if
8121 new count is bigger or equal than original before emitting any
8122 statements, rather than during that. Remove no longer needed
8123 new_ssa_names tracking. Replace num_stmts with
8124 split_stores.length (). Use 32-bit stack allocated entries
8125 in split_stores auto_vec. Try to reuse original store lhs/rhs1
8126 if possible. Handle bitfields with gaps.
8127 (pass_store_merging::execute): Ignore bitsize == 0 stores.
8128 Compute bitregion_{start,end} for the stores and construct
8129 store_immediate_info with that. Formatting fixes.

35220 support for predefined __POWER9_VECTOR__ macro to indicate that

35226 entry for overloaded function argument types RS6000_BTI_bool_V4SI
35227 andRS6000_BTI_bool_V4SI, mapping to P9V_BUILTIN_CMPNEB. Remove
35228 two entries mapping to P9V_BUITIN_CMPNED and one entry mapping to
35229 P9V_BUILTIN_CMPNEF to force use of instructions not specific to
35230 Power9 for implementations of vec_cmpne. Change the signature for
35231 all definitions of the overloaded P9V_BUILTIN_VEC_CMPNE_P function
35232 (representing vec_all_ne) to remove the previously described first
35233 argument of type RS6000_BTI_INTSI, as this was an artifact of
35234 reliance on the AltiVec predicate framework, which is no longer
35235 used in the implementation of these functions. Add
35236 P9V_BUILTIN_VEC_VCMPAE_P entries (representing the vec_anyeq
35237 function) to match all of the P9V_BUILTIN_VEC_VCMNE_P entries
35238 since, unlike the AltiVec predicate framework implementation, we
