	* config/mips/tm-irix5.h: Modify to work better on irix 6, by
	making FP registers 8 bytes instead of 4.
	REGISTER_BYTES: redefine.  REGISTER_BYTE(): redefine.
	REGISTER_VIRTUAL_TYPE: redefine.  MIPS_LAST_ARG_REGNUM: redefine.
	* irix5-nat.c (fetch_core_registers): read 8 bytes per FP register.
	* mips-tdep.c (FP_REGISTER_DOUBLE): new macro to distinguish
	targets with 8-byte FP registers (don't use TARGET_MIPS64).
	(STACK_ARGSIZE): new macro, how much space is taken up on the
	stack for each function argument (don't use TARGET_MIPS64).
	(mips_push_arguments): modify logic to work better on Irix 6
	(n32 ABI).
