With bundle alignment, instructions all get their own MCFragments (unless they are in a bundle-locked group). For instructions with fixups, this is an MCDataFragment. Emitting actual data (e.g. for .long) attempts to re-use MCDataFragments, which we don't want int this case since it leads to fragments which exceed the bundle size. So, don't reuse them in this case. Also adds a test and fixes some formatting. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175316 91177308-0d34-0410-b5e6-96231b3b80d8
