Implement MachOObjectFile::isSectionData() and MachOObjectFile::isSectionBSS
so that llvm-size will total up all the sections in the Berkeley format. This allows for rough categorizations for Mach-O sections. And allows the total of llvm-size’s Berkeley and System V formats to be the same. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209158 91177308-0d34-0410-b5e6-96231b3b80d8
