This calls into the existing constant folding for `llvm.sin` and `llvm.cos`, which currently does not fold for any non-finite values, so most tests are negative tests at the moment. Note: The constant folding does not consider the `afn` fast-math flag and will produce the same result regardless of if the flag is set. This is a reland of #114527 that updates the syntax of one of the tests from: `<float 1.000000e+00, float 1.000000e+00>` to `splat (float 1.000000e+00)`.
