Fix incorrect invariant check in DAG Combine Earlier this summer I fixed an issue where we were incorrectly combining multiple loads that had different constraints such alignment, invariance, temporality, etc. Apparently in one case I made copt paste error and swapped alignment and invariance. Tests included. rdar://18816719 llvm-svn: 220933

Similar migration script can be used to update test cases, which successfully migrated all of LLVM and Polly, but about 4 test cases needed manually changes in Clang.
