The LoongArch psABI recently added __bf16 type support. Now we can enable this new type in clang. Currently, bf16 operations are automatically supported by promoting to float. This patch adds bf16 support by ensuring that load extension / truncate store operations are properly expanded. And this commit implements support for bf16 truncate/extend on hard FP targets. The extend operation is implemented by a shift just as in the standard legalization. This requires custom lowering of the truncate libcall on hard float ABIs (the normal libcall code path is used on soft ABIs).
