We are seeing many errors for this:
7680x error: 'dx.op.dot4AddPacked' is not a DXILOpFuncition for DXILOpcode 'Dot4AddU8Packed'.
7680x error: 'dx.op.dot4AddPacked' is not a DXILOpFuncition for DXILOpcode 'Dot4AddI8Packed'.
48x error: External function 'dx.op.dot4AddPacked.i32' is unused.
The fix seems to be to set the result type to `OverloadTy` see: https://github.com/llvm/llvm-project/commit/90a97c4c68ffe8f0329d5f3f69f41da66e5e05e2
