X86: Do not use llc -march in tests. `llc -march` is problematic because it only switches the target architecture, but leaves the operating system unchanged. This occasionally leads to indeterministic tests because the OS from LLVM_DEFAULT_TARGET_TRIPLE is used. However we can simply always use `llc -mtriple` instead. This changes all the tests to do this to avoid people using -march when they copy and paste parts of tests. See also the discussion in https://reviews.llvm.org/D35287 llvm-svn: 309774

AVX-512: dec/inc instructions are slow on KNL After Alexey Volkov, I'm adding the same property for KNL, that prefers ADD/SUB instead of INC/DEC. Added a test. llvm-svn: 212178
