Thiago Macieira 280e321e52 Fix detection of F16C for the Intel compiler (again) and Visual Studio ... Neither the Intel compiler nor Visual C++ have a dedicated switch to enable F16C support, like GCC and Clang do. So we used the AVX switch for that in commit 8241d51f70, as it was the closest, lowest denominator. That was incorrect and insufficient. The Intel compiler silently miscompiles the intrinsics with -xAVX, making calls to out-of-line functions like _mm_cvtps_ph, which don't exist. So we actually have to use AVX2 support to generate correct code. That might be a problem later, since Ivy Bridge supports F16C but not AVX2. Visual C++ is able to generate F16C code with just -arch:AVX. Either way, since there's no dedicated command-line switch, there's also no dedicated preprocessor macro. We're using __AVX2__ for both compilers, as that's a sufficient condition to indicate a processor that supports F16C.
