Sameer Sahasrabuddhe 7c760b224b Restore "[GlobalISel] GIntrinsic subclass to represent intrinsics in Generic Machine IR" ...

Some opcodes in generic MIR represent calls to intrinsics, where the intrinsic
ID is the first non-def operand to the instruction. These are now represented as
a subclass of GenericMachineInstr, and the method MachineInstr::getIntrinsicID()
is now moved to this subclass GIntrinsic.

Some target-defined instructions behave like GMIR intrinsics, and have an
Intrinsic::ID operand. But they should not be recognized as generic intrinsics,
and should not use GIntrinsic::getIntrinsicID(). Separated these out by
introducing a new AMDGPU::getIntrinsicID().
