Hello,

This eliminates the macro MIPS_REGISTER_NAMES by adding a field 
"mips_processor_reg_names" to the "tdep" and setting that according to 
the OSABI/cpu.

Further, since it turns out that the global "mips_processor_regnames" 
can only be changed to r3041 (via remote-mips.c) I've replaced the mips 
processor names table by deprecated_mips_set_processor_regs_hack().

committed,
Andrew
