        PR middle-end/59134
        * expmed.c (store_bit_field): Use narrow_bit_field_mem and
        store_fixed_bit_field_1 for -fstrict-volatile-bitfields.
        (store_fixed_bit_field): Split up.  Call store_fixed_bit_field_1
        to do the real work.
        (store_fixed_bit_field_1): New function.
        (store_split_bit_field): Limit the unit size to the memory mode size,
        to prevent recursion.
        
testsuite:
        * gcc.c-torture/compile/pr59134.c: New test.
        * gnat.dg/misaligned_volatile.adb: New test.
