5701 from bitregion_start instead of start. Compute allow_unaligned
5702 here, if true, do 2 split_group dry runs to compute which one

5704 new count is bigger or equal than original before emitting any
5705 statements, rather than during that. Remove no longer needed
5706 new_ssa_names tracking. Replace num_stmts with
5707 split_stores.length (). Use 32-bit stack allocated entries
5708 in split_stores auto_vec. Try to reuse original store lhs/rhs1
5709 if possible. Handle bitfields with gaps.
