Cherry Zhang 0938e4cf90 cmd/internal/obj/mips: support NEG, avoid crash with illegal instruction
Add support of NEG{V,W} pseudo-instructions, which are translated
to a SUB instruction from R0 with proper width.

Also turn illegal instruction to UNDEF, to avoid crashing in
asmout when it tries to read the operands.

Fixes #23548.
