Rollup merge of #144987 - tgross35:llvm21-f16-f128, r=nikic
Enable f16 and f128 on targets that were fixed in LLVM21

LLVM21 fixed the new float types on a number of targets:

* SystemZ gained f16 support  https://github.com/llvm/llvm-project/pull/109164
* Hexagon now uses soft f16 to avoid recursion bugs  https://github.com/llvm/llvm-project/pull/130977
* Mips now correctly handles f128 (actually since LLVM20) https://github.com/llvm/llvm-project/pull/117525
* f128 is now correctly aligned when passing the stack on x86  https://github.com/llvm/llvm-project/pull/138092

Thus, enable the types on relevant targets for LLVM > 21.0.0.

NVPTX also gained handling of f128 as a storage type, but it lacks support for basic math operations so is still disabled here.
