Auto merge ofrust-lang#127027 - tgross35:f16-f128-math, r=<try>
Add `f16` and `f128` math functionsWIPThis will be pretty finicky among selection failures, the lowering bug, and lack of symbols. But might as well start somewhere.Checks will fail untilrust-lang#126636 makes it to beta, which should be next week (July 19).try-job: aarch64-gnu
