Validate and reject any unknown or unavailable instruction mnemonics early in ParseInstruction, before any operand parsing is performed. Some operands (mainly memory ones) can be parsed slightly differently in V8 and V9 assembly language, so by rejecting unknown or unavailable instructions early we can prevent the error message from being shadowed by the one raised during operand parsing. As a side effect this also allows us to tell unknown and unavailable mnemonics apart, and issue a suggestion in appropriate cases. This is based on the approach taken by the MIPS backend.
