We actually use `_Float16` (`Float16Type`) in the public header, but this needs to match the name of the header in llvm-libc-types for libc-hdrgen to generate the #include line.

Or should we split the `LIBC_TYPES_HAS_FLOAT16` macro and the `float16` type alias into 2 separate headers, as we said we'd only use `float16` internally?
