  AMDGPU: Assume true in getVOPNIsSingle helpers

If we have something we don't know what it is, we should conservatively
avoid printing an additional suffix. For isCodeGenOnly pseudoinstructions,
no encoded instruction is added to the tables this is queried, and the null
case would assume true.

This happens to fix the case I ran into, but this isn't a wholistic fix.
These really should be encoded directly in the TSFlags of the MCInstrDesc,
which would allow encoding pseudos to work correctly.
