Add an intrinsic like this one from https://github.com/llvm/llvm-project/blob/1e6ce5e284f5c0e8d64eee21af727bb164eb3caf/llvm/include/llvm/IR/IntrinsicsDirectX.td#L28
to
https://github.com/llvm/llvm-project/blob/1e6ce5e284f5c0e8d64eee21af727bb164eb3caf/llvm/include/llvm/IR/IntrinsicsSPIRV.td#L59
We won't need dot2,dot3,dot4 for spirv which adds a bit of a complication on our switching, Come with an intrinsic switching behavior that allows for per backend specializations. maybe as a per backend lambda?
update the dot.hlsl unit tests:
https://github.com/llvm/llvm-project/blob/1e6ce5e284f5c0e8d64eee21af727bb164eb3caf/clang/test/CodeGenHLSL/builtins/dot.hlsl#L1
and implement the `OpDot` Lowering:
