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.

Fix pr11266. On x86: (shl V, 1) -> add V,V Hardware support for vector-shift is sparse and in many cases we scalarize the result. Additionally, on sandybridge padd is faster than shl. llvm-svn: 143311 2011-10-30 14:24:22 +01:00
Update to more CodeGen tests to use CHECK-LABEL for labels corresponding to function definitions for more informative error messages. No functionality change.
