see `clang/test/CodeGenHLSL/builtins/dot.hlsl` that should let you use CHECK
for most of your intrinsics so we don't have to do so many seperate SPIRV vs
DX checks.
should look something like this for the first one
// DXCHECK: %na,e = call <type> @llvm.[[ICF:dx]].<intrinsic_name>.<type>(..
// SPVCHECK: %name = call <type> @llvm.[[ICF:spv]].<intrinsic_name>.<type>(...
