Improve the generic MIR in the default `PartialOrd::le` and friends It looks like I regressed this accidentally in #137197 due to #137901 So this PR does two things: 1. Tweaks the way we're calling `is_some_and` so that it optimizes in the generic MIR (rather than needing to optimize it in every monomorphization) -- the first commit adds a MIR test, so you can see the difference in the second commit. 2. Updates the implementations of `is_le` and friends to be slightly simpler, and parallel how clang does them.
