* 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).
