Add functions for fast bulk conversion of qfloat16
Both ARM and x86 can convert fp16 much faster in bulk than one at a time. This also enables hardware accelerated conversion on x86, when F16C isn't unconditionally available at compile time. This code is implemented in C to ensure that there's no leakage of inline symbols from the .obj file that was compiled by Visual Studio with AVX support. Unfortunately, simd.prf uses $(CXX) instead of $(CC) for all its sources, which means the file gets interpreted as C++ by g++, clang++ and icpc. Those compilers at least don't leak any symbols.
