* emit-rtl.c (gen_int_mode): New function.
        * rtl.h: Prototype for it.
        * combine.c (make_extraction, simplify_comparison), expmed.c
        (store_bit_field, expand_mult_highpart, expand_divmod), expr.c
        (convert_modes, store_field), optabs.c (expand_fix),
        simplify-rtx.c (neg_const_int, simplify_unary_real),

        * config/rs6000/rs6000.c, config/rs6000/rs6000.md:
        Use it instead of GEN_INT (trunc_int_for_mode (...)).
