[dev.ssa] cmd/compile/internal/ssa: autogenerate opcodes
Revamp autogeneration. Get rid of gogenerate commands, they are more
trouble than they are worth. (If the code won't compile, gogenerate
doesn't work.)
Generate opcode enums & tables. This means we only have to specify
opcodes in one place instead of two.
Add arch prefixes to opcodes so they will be globally unique.
