alignment is ignored, and they always allocate a complete storage unit. Also, change the dumping of AST record layouts: use the more readable C++-style dumping even in C, include bitfield offset information in the dump, and don't print sizeof/alignof information for fields of record type, since we don't do so for bases or other kinds of field. rdar://22275433 llvm-svn: 245514
