Add powi to f16 and f128

This will unblock adding support to compiler_builtins
(<rust-lang/compiler-builtins#614>), which will
then unblock adding tests for these new functions.

Add `powi` fo `f16` and `f128`

This will unblock adding support to compiler_builtins (<rust-lang/compiler-builtins#614>), which will then unblock adding tests for these new functions.

WIndows targets appear to fail compiling this crate because powi uses the f128 multiply and divide in its implementation, and these are not available. I don't know why only Windows has the issue, but other platforms without these available natively (e.g. aarch darwin) do not, must be slightly different linkage rules. How should I handle this @Amanieu?

I think this just happens to work before libgcc provides these symbols, but that's not available on -msvc targets. You'll need to implement a fallback for that target for testing, at least temporarily.

It looks like I can make this work by recreating __multf3 and __divtf3 in testcrate's lib.rs, this will just be blocked until I implement divtf3.

__divtf3 hasn't made it to nightly yet, and I can't seem to figure out a way to provide it here to avoid the Windows linking. Hopefully that won't be too far off, but I just disabled this new symbol on MSVC in the meantime.

This should be ready for a look when you get the chance @Amanieu

LGTM. Feel free to merge it either now (and enable it with MSVC later) or after a boostrap bump.

Thanks! rust-lang/rust#130792 hasn't been picked up yet so I might as well just update that to include this.
