// There are no tests yet for instructions that use 512-bit wide registers because they are not
// supported by some compilers yet.
// Relevant review in LLVM https://reviews.llvm.org/D16757, we should wait untill it will be in our
// version of Clang.
//
// There are also no tests for PREFETCHWT1, PCOMMIT, CLFLUSHOPT and CLWB as they are not supported
// by our compilers yet (and there are no available processors yet :).
