Changed the TableGen created MatchInstructionImpl() setting of ErrorInfo.

The algorithm for identifying which operand is invalid will now always point to
some operand and not the mnemonic sometimes.  The change is now that ErrorInfo
is the index of the highest operand that does not match for any of the matching
mnemonics records.  And no longer the ~0U value when the mnemonic matches and
not every record with a matching mnemonic has the same mismatching operand
index.
