  -----------
  [clang][LoongArch] Add support for the _Float16 type (#141703)

Enable _Float16 for LoongArch target. Additionally, this change fixes
incorrect ABI lowering of _Float16 in the case of structs containing
fp16 that are eligible for passing via GPR+FPR or FPR+FPR. Finally, it
also fixes int16 -> __fp16 conversion code gen, which uses generic LLVM
IR rather than llvm.convert.to.fp16 intrinsics.
