Silence cl.exe warning about -arch:SSE2 being unknown in 64-bit builds That implies we need to differentiate between a variable set but empty and an empty variable. GCC, Clang and the Intel compiler accept -msse2 on 64-bit builds without warning (they also accept -mno-sse2), but the Microsoft compiler does not have that option.

Add support for AVX-512 intrinsics found in MSVC 2017 15.3 It seems the compiler supports /arch:AVX512 and /arch:AVX512F but none of the other switches (and neither are documented). And when you pass those, you also get Conflict Detection (CD), Double & Quad (DQ), Byte & Word (BW) and Vector Length (VL), which matches the ICC switch "-xCORE-AVX512". Unlike ICC, there doesn't seem to be an option to enable only the common part of AVX-512. Support for Intel Xeon Phi's current features (Exponential & Reciprocation and Prefetch) and future ones (IFMA, VBMI, 4FMAPS, 4VNNI and VPOPCNTDQ) seems to be missing altogether.
