[SPARC][IAS] Reject unknown/unavailable mnemonics early in ParseInstruction
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.
