symbolic register names for MIPS

[William Lee Irwin III]

The patch at http://holomorphy.com/~wli/scripts/tc-mips.c.patch
implements some changes to accept symbolic register names like the
Algorithmics assembler, following the documentation given in
Patterson & Hennessy's "Computer Organization & Design: The Hardware
/ Software Interface", Appendix A, section A.6, Figure A.9, page A-23.

This makes assembly language programming on the MIPS architecture
somewhat easier for me. I hope it's useful for others as well.


Thanks,
Bill
