nanomips-linux-musl-objdump always shows three registers and generic mnemonic
AND (without [16]).
On the other hand, inline assembler accepts syntax with two registers or/and
instruction format specification.
We should decide whether we should follow objdump or assembler conventions.
In any case, the same rule should be applied consistently across this
disassembler.
