The signature for this intrinsic is different in DX and SPIRV by design. As
discussed here:
https://github.com/llvm/llvm-project/pull/114588#discussion_r1828324074,
`SPIRVInstructionSelector.cpp` doesn't support creating new basic blocks. So
after discussing with @farzonl, we came to a conclusion that, in order to not
introduce new patterns to intrisic creations, we are handling most of the
codegen and `CGBuiltin.cpp`. As a consequence, the codegen requires those
intrinsic to have different signatures.
