* config/tc-mips.c: Remove all the mips_NNNN variables; just use
mips_cpu instead. (mips_4650, mips_4010, mips_4100): Variables removed. start-sanitize-vr4xxx (mips_4121): Variable removed. end-sanitize-vr4xxx start-sanitize-vr4320 (mips_4320): Variable removed. end-sanitize-vr4320 start-sanitize-cygnus (mips_5400): Variable removed. end-sanitize-cygnus start-sanitize-r5900 (mips_5900): Variable removed. end-sanitize-r5900 start-sanitize-tx49 (mips_4900): Variable removed. end-sanitize-tx49 (hilo_interlocks, gpr_interlocks, append_insn, macro_build, macro, macro2, mips16_macro, mips_ip): Test mips_cpu, not the mips_NNNN variables. (md_begin): Don't bother initializing the mips_NNNN variables; mips_cpu is set, and that's good enough now. (md_parse_option): Have the -mNNNN options set mips_cpu instead of the mips_NNNN variable. The -no-mNNNN flags are now no-ops. (show): New function, to handle wrapping in the CPU lists. (md_show_usage): Update lists of -mcpu and -mNNNN switches.
