When a struct has bitfields overlapping with other members (as required by the AAPCS), clang uses a packed struct to represent this. If such a struct is large enough for clang to pass it as a byval pointer (>64 bytes), we need to set the alignment of the argument to match the original type. llvm-svn: 203660
