COP0_SYNC In R5900 mtc0, tlbr, tlbp, tlbwi, tlbwr must be followed by sync.p. if defined MIPS3_5900, COP0_SYNC is defined as sync.p. else nothing. IPL_ICU_MASK mask interrupt directly ICU instead of SR.IM. I've added this feature to support software interrupt for R5900. and this option may be useful for platform which has cascaded ICU.
