* mips.md (reload_outsi): Added missing REGNO call.
(smulsi3_highpart, umulsi3_highpart): Provide prototype for function pointer.
(mul_acc_di, mul_acc_64bit_di): Don't use match_op_dup, use another
match_operator and compare the codes.
* mips.h (MASK_DEBUG_E, MASK_DEBUG_I): Set to zero.
* MIPS multiply pattern fixes:
* mips.h (enum reg_class, REG_CLASS_NAMES, REG_CLASS_CONTENTS): Add union
classes for HI, LO, or HILO plus general registers.
(GENERATE_MADD): Deleted.
* mips.md (mulsi3_mult3): Don't disparage output-LO alternative.  Add
TARGET_MAD to condition.
(mulsi3): Test HAVE_mulsi3_mult3, not specific flags.
(mul_acc_si): Expand GENERATE_MADD here; it's the only use.  Use "*d" for
accumulator, to give preference to LO initially but not during reload.
