Add "algebraic" fast-math intrinsics, based on fast-math ops that cannot return poison Setting all of LLVM's fast-math flags makes our fast-math intrinsics very dangerous, because some inputs are UB. This set of flags permits common algebraic transformations, but according to the [LangRef](https://llvm.org/docs/LangRef.html#fastmath), only the flags `nnan` (no nans) and `ninf` (no infs) can produce poison. And this uses the algebraic float ops to fix https://github.com/rust-lang/rust/issues/120720 cc `@orlp` |
