expmed.c (store_bit_field): Pun non-integral str_rtx modes.
* expmed.c (store_bit_field): Pun non-integral str_rtx modes.
Take extra care for op0 now possibly being a subreg.
(extract_bit_field): Likewise.
* function.c (purge_addressof_1): Revert Oct 4 change. Drop
the reg to memory if there is no equal sized integral mode.
* stor-layout.c (int_mode_for_mode): New function.
* machmode.h: Prototype it.
