LoongArch Support
^^^^^^^^^^^^^^^^^

- Add support for OHOS on loongarch64.

- Add target attribute support for function. Supported formats include:
* `arch=<arch>` strings - specifies architecture features for a function (equivalent to `-march=<arch>`).
* `tune=<cpu>` strings - specifies the tune CPU for a function (equivalent to `-mtune`).
* `<feature>`/`no-<feature>` - enables/disables specific features.

- Add support for the `_Float16` type. And fix incorrect ABI lowering of `_Float16`
in the case of structs containing fp16 that are eligible for passing via `GPR+FPR`
or `FPR+FPR`. Also fix `int16` -> `__fp16` conversion code gen, which uses generic LLVM
IR rather than `llvm.convert.to.fp16` intrinsics.

- Add support for the `__bf16` type.

- Fix incorrect _BitInt(N>64) alignment. Now consistently uses 16-byte alignment for all
`_BitInt(N)` where N > 64.

RISC-V Support
