Revert the test moves from 176733. Use "REQUIRES: asserts" instead. llvm-svn: 176873

; REQUIRES: asserts
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

Mark functions in some tests as 'nounwind'. Generating EH info for these functions causes the tests to fail for random reasons (e.g. looking for 'or' or counting lines with asm-printer; labels count as lines.) llvm-svn: 49003

Mass update to CodeGen tests to use CHECK-LABEL for labels corresponding to function definitions for more informative error messages. No functionality change and all updated tests passed locally.
