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 2017-08-02 08:28:10 +08:00			`; RUN: llc < %s -mtriple=x86_64-- -mattr=-avx \| grep movq \| count 2`

ensure we don't regress on these tests. We generate aweful code in x86-32 for these though. llvm-svn: 37619 2007-06-18 07:29:57 +08:00
