This patch adds both extendhftf2 and trunctfhf2 to support conversion between half-precision and quad-precision floating-point values. They are built iff the compiler supports _Float16. Some notes on ARM plaforms: while fp16 is supported on all architectures, _Float16 is supported only for 32-bit ARM, 64-bit ARM, and SPIR (as indicated by clang/docs/LanguageExtensions.rst). Also, fp16 is a storage format and 64-bit ARM supports floating-point convert precision to half as base armv8-a instruction. This patch does not change the ABI for 32-bit ARM, it will continue to pass _Float16 as uint16.
