        * expr.c (store_expr): Assume lang_hooks.reduce_bit_field_operations
        is true.
        (expand_expr_real_1) <REDUCE_BIT_FIELD>: Don't look at ignore.
        (expand_expr_real_1): Assume lang_hooks.reduce_bit_field_operations
        is true.  Add "&& !ignore" condition to reduce_bit_field.  Modify
        target after ignore has been set, and move there also the commputation
        of subtarget and original_target.
        * langhooks-def.h (LANG_HOOKS_REDUCE_BIT_FIELD_OPERATIONS): Delete.
        (LANG_HOOKS_INITIALIZER): Remove it.
        * langhooks.h (struct lang_hooks): Remove reduce_bit_field_operations.
