[dev.ssa] cmd/compile/internal/ssa: implement lots of small (<8byte) ops.
Lots and lots of ops!
Also XOR for good measure.
Add a pass to the compiler generator to check that all of the
architecture-specific opcodes are handled by genValue. We will
catch any missing ones if we come across them during compilation,
but probably better to catch them statically.
