FloatTy in rustc has f16 and f128 now. It would probably be pretty easy to update RA's FloatTy to match and propagate that out.

    That will require changes to chalk

    Now that #17572 has been merged, all that's left for this issue is to:

    • Add support for f16/f128 intrinsics.
    • Replace rustc_apfloat with the types themselves once they've been stabilised.

    Most of the former will probably require the later since rustc_apfloat only supports basic arithmetic operations.
