re PR rtl-optimization/55388 (ICE in int_mode_for_mode at stor-layout.c:423)
PR rtl-optimization/55388
* alias.c (nonoverlapping_component_refs_p): Handle bitfields.
* emit-rtl.c (adjust_address_1): Deal with VOIDmode early.
* expmed.c (store_bit_field): Turn the call to adjust_address
into a call to adjust_bitfield_address_size.
