[AMDGPU] Fix Ins64 clamp in the VOPProfile. NFC.

[rampitec]

For some reason only IntClamp was added to the Ins64, bit not FPClamp. As is this is NFC, but fails to produce proper dag downstream.

There's another use of HasIntClamp in VOP3_Pseudo in VOPInstructions.td:

  let AsmMatchConverter =
    !if(isVOP3P,
        "cvtVOP3P",
        !if(!or(P.HasModifiers, P.HasOMod, P.HasIntClamp),
            "cvtVOP3",
            ""));

Does that also need changing?

Yes, nothing breaks if I use HasClamp.
