When expanding a truncating store or extending load using vector extracts or inserts and scalar stores and loads, we were giving each of these scalar stores or loads the same alignment as the original vector operation. While this will often be right (most vector operations, especially those produced by autovectorization, have the alignment of the underlying scalar type), the vector operation could certainly have a larger alignment. No test case (yet); noticed by inspection. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@230175 91177308-0d34-0410-b5e6-96231b3b80d8
