- Flip order of bitfields. This gets our output matching GAS. - Handle case where the end of the prolog wasn't specified. - If the resulting unwind info struct is less than 8 bytes, pad to 8 bytes. Add a test for the latter two. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132188 91177308-0d34-0410-b5e6-96231b3b80d8
