My reasoning for this approach was that certain DXIL intrinsics doesn't have
1:1 mapping to SPIRV intrinsics. `WaveActiveSum` and `WavePrefixSum` (this PR)
have both `usum` and `sum` DXIL intrinsics but in SPIRV is just `sum`. I was
trying to come up with a proper solution that could fix all the static
functions to get the intrinsics in `CGHLSLBuiltins.cpp`
