Merge all the existing checks into a single one, which is a simple pass or fail, since all our supported compilers support all the intrinsics up to Cannon Lake. The two I've recently added (AVX512VBMI2 and VAES) aren't yet supported everywhere, so they stay. For some reason, all intrinsics seem to be disabled on Android. It looks like some support was missing during the CMake port and this was never again looked at. I'm leaving it be. As for WASM, discussion with maintainers is that the WASM emulation of x86 intrinsics is too hit-and-miss. No one is testing the performance, particularly the person writing such code (me). They also have some non-obvious selection of what is supported natively and what is merely emulated. Using the actual WASM intrinsics is preferred, but someone else's job.
