7283 if there is exactly a single original stmt. Change stmts argument
7284 to pointer from reference, if NULL, don't push anything to it. Add
7285 first argument, use it to optimize skipping over orig stmts that
7286 are known to be before bitpos already. Simplify.
7287 (split_group): Return unsigned int count how many stores are or
7288 would be needed rather than a bool. Add allow_unaligned argument.
7289 Change split_stores argument from reference to pointer, if NULL,
7290 only do a dry run computing how many stores would be produced.
7291 Rewritten algorithm to use both alignment and misalign if
7292 !allow_unaligned and handle bitfield stores with gaps.

7297 new count is bigger or equal than original before emitting any
7298 statements, rather than during that. Remove no longer needed
7299 new_ssa_names tracking. Replace num_stmts with
7300 split_stores.length (). Use 32-bit stack allocated entries
7301 in split_stores auto_vec. Try to reuse original store lhs/rhs1
7302 if possible. Handle bitfields with gaps.
