  Reland "[InstSimplify] Add basic constant folding for `llvm.sincos`" (#119192)

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)`.
