Subject: WIP HLSL intrinsic coverage (#1171)

* Added hlsl-intrinsic test folder.
Enabled ceil as works across targets.

* log10 support.

* Fix float % on CPU/CUDA to match HLSL which is fmod (not fremainder).

* Added log10 tests back to scalar-float.slang

* Don't add the ( for $Sx - it's clearer what's going on without it.

* Works on CUDA/CPU. Problem with asint/asuint do not seem to be found.

* Only asuint exists for double.

* Support countbits on CUDA and C++.

* Fix typo in C++ population count.

* First pass at int vector intrinsic tests.

* Swizzle for int.

* Bit cast tests on CUDA.

* Fix warning on gcc.

* Fix bit-cast-double execution on CUDA.

* scalar-int test working on gcc release.
