Instead of detecting `_Float16` support at CMake configuration time, detect it at compile time by checking for the predefined (by the compiler) macro `__FLT16_MAX__` instead. This solves the issue where compiler-rt is built simultaneously for both x86_64 and i386 targets, and the CMake configuration uses x86_64 compilation to detect `_Float16` support, while it may not be supported by the i386 target (if it does not have SSE2). While here, rename `COMPILERT_RT_HAS_FLOAT16` to `CRT_HAS_FLOAT16`, to conform more to the naming style used in `int_lib.h` and `int_types.h`.
