; NOTE: Assertions have been autogenerated by utils/update_llc_test_checks.py
Fix line ending in test CodeGen/X86/pr22774.ll. NFC. Also, replaced line with 'target triple' with flag -mtriple on the RUN line. Removed the data layout string as it is not needed. llvm-svn: 231654

[DAGCombine] Fix a bug in a BUILD_VECTOR combine When trying to convert a BUILD_VECTOR into a shuffle, we try to split a single source vector that is twice as wide as the destination vector. We can not do this when we also need the zero vector to create a blend. This fixes PR22774. Differential Revision: http://reviews.llvm.org/D8040 llvm-svn: 231219
