I was debating exactly this choice. I think it's already relatively simple to check `isParsingMasm()` and then cast the parser object back to `MasmParser` if you need to ask specific questions of it.

However, the Context object seemed a natural place to store stateful context affecting the meaning of potentially-ambiguous mnemonics. I take it you think this is a bit too MASM-specific, and that no other MC should expect to have to make this differentiation contextually?
