I didn't really think about optimization, but I did not 
understand what/how user-regs is being used. Now I realize 
that is the mechanism for adding register aliases.

Here is another try.

(again, tested on in-house gdb variant).

ChangeLog:


* mips-tdep.c (mips_numeric_register_alieses): New definition.
(mips_gdbarch_init): Add user registers from
mips_numeric_register_aliases.
