Before commit:
commit 2438b771ee07be19d5b01ea55e077dd8b7cef445
Date: Wed Nov 2 15:53:43 2022 +0000
opcodes/mips: use .word/.short for undefined instructions
unknown 32-bit microMIPS instructions were disassembled as a raw
32-bit number with no '.word' directive. The above commit changed
this and added a '.word' directive before the 32-bit number.
It was pointed out on the mailing list, that for microMIPS it would be
better to display such 32-bit instructions using a '.short' directive
followed by two 16-bit values.
This commit updates the mips disassembler to do this, and adds a new
test that validates this output.
