AMDGPU: Consistently check for immediates in SIInstrInfo::FoldImmediate
Summary:
The PeepholeOptimizer pass calls this function solely based on checking
DefMI->isMoveImmediate(), which only checks the MoveImm bit of the
instruction description. So it's up to FoldImmediate itself to properly
check that DefMI *actually* moves from an immediate.
I don't have a separate test case for this, but the next patch introduces
a test case which happens to crash without this change.
This error is caught by the assertion in MachineOperand::getImm().
