This patch adds two new CIR floating-point types, namely `!cir.f16` and `!cir.bf16`, to represent the float16 format and bfloat format, respectively. CIRGen for the two new types and scalar expressions involving these two new types is also included in this patch. This patch converts the clang extension type `_Float16` to `!cir.f16`, and converts the clang extension type `__bf16` type to `!cir.bf16`.

There was a problem hiding this comment.
Great, thanks for all the promotion related improvements, they are very nice.
LLVMIR lowering, and MLIR lowering for the two new types are also included in this PR.
Fine for this, but for next PRs I might start getting more picky about adding LLVM IR checks, the unary questions below are one example where checking intended LLVM output could have made some of the choices easier.

This PR converts the clang extension type `_Float16` to `!cir.f16`, and converts the clang extension type `__bf16` type to `!cir.bf16`. The type conversion for clang extension type `__fp16` is not included in this PR since it requires additional work during CIRGen. Only CIRGen is implemented here, LLVMIR lowering / MLIR lowering should come next.
