This change exposes the reversebits library function for HLSL, excluding floating point types. The reversebits function is supported for all scalar, vector, and matrix types. The full documentation of the HLSL reversebits function is available here: https://learn.microsoft.com/en-us/windows/win32/direct3dhlsl/reversebits Reviewed By: python3kgae Differential Revision: https://reviews.llvm.org/D156933
