[PATCH] D49987: [ARM] Make FP16 vectors legal

I have added a hardfp test. Clang has some logic to handle scalar FP16 values, it performs softening when needed (e.g. tools/clang/test/CodeGen/arm-fp16-arguments.c), whereas NEON vectors are lowered into LLVM vector types. So we don't need additional changes neither in Clang nor in the LLVM scalar FP16 handing.
