* mips-tdep.c (mips_register_type): Simplify. Eliminate reference
to MIPS_REGISTER_TYPE. Make integer registers signed. Make IRIX
n32 registers 64 bit.
(mips_register_raw_size, mips_register_byte): For pseudo
registers, use the register's pseudo size and not the
corresponding raw register's size.
* config/mips/tm-mips64.h (MIPS_REGISTER_TYPE): Delete macro.
* config/mips/tm-mips.h (MIPS_REGISTER_TYPE): Delete macro.
* config/mips/tm-irix6.h: Don't #undef MIPS_REGISTER_TYPE.
* config/mips/tm-irix5.h (MIPS_REGISTER_TYPE): Delete macro.
