* expr.c (store_field): Avoid a direct store if the mode is larger
than the size of the bit field.
* stor-layout.c (layout_decl): If flag_strict_volatile_bitfields,
treat non-volatile bit fields like volatile ones.
* toplev.c (process_options): Disallow combination of
-fstrict-volatile-bitfields and ABI versions less than 2.
* config/arm/arm.c (arm_option_override): Don't enable
flag_strict_volatile_bitfields if the ABI version is less than 2.
* config/h8300/h8300.c (h8300_option_override): Likewise.
* config/rx/rx.c (rx_option_override): Likewise.
* config/m32c/m32c.c (m32c_option_override): Likewise.
