uch d8c8db85ef R5900 support.
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.
