LGTM, cheers.

Just curious, but what happens if MUL VL is excluded? Is it just syntactic sugar?

If the 'mul vl' is omitted you get an invalid operand on the ']' token. Basically, the ', mul vl' is parsed and re-inserted as a literal string token (in parseOptionalMulVl), which is then matched to the literal string in the instruction definition.
