I don't beleive fclamp is correct for HLSL. I beleive HLSL uses NClamp since
max and min are NMin and NMax.
We had to fix a bug like this in the past.

Either we make a spv_nclamp and use that in CGBuiltins.cpp or we just change
this line to:
```suggestion
return selectExtInst(ResVReg, ResType, I, CL::nclamp, GL::NClamp);
```
