* i386.h (SPECIAL_MODE_PREDICATES): New.
        * i386.md (movstricthi_1): Use nonimmediate_operand for op 0.
        (movqi_1, movdi_1, movdi_2, some splits): Likewise.
        (addsi_lea_3): Add missing mode for op 3.
        (prologue_set_got, prologue_get_pc): Add missing modes.
        (*) Add missing output reload constraints.
