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

Make EXTRACT_VECTOR_ELT a bit more flexible in terms of the returned value. Adjust other code to deal with that correctly. Make DAGTypeLegalizer::PromoteIntRes_EXTRACT_VECTOR_ELT take advantage of this new flexibility to simplify the code and make it deal with unusual vectors (like <4 x i1>) correctly. Fixes PR3037. llvm-svn: 75176
