This work needs to come after: https://github.com/llvm/llvm-project/issues/87776
once we have `llvm.frexp` we need to test if the support alreadt exists. If it doesn't we need to add it.
update the frac.hlsl unit tests:
https://github.com/llvm/llvm-project/blob/1e6ce5e284f5c0e8d64eee21af727bb164eb3caf/clang/test/CodeGenHLSL/builtins/frac.hlsl#L2
example:
https://shader-playground.timjones.io/020254826814c6bfb01e671c08c15db4
and implement the `OpExtInst Fract` Lowering:
`%13 = OpExtInst %v4float %1 Fract %12`
