should have no state that is specific to particular globals in the section. In this case, it means the removal of the "isWeak" and "ExplicitSection" bits. MCSection uses the new form of SectionKind. To handle isWeak, I introduced a new SectionInfo class, which is SectionKind + isWeak, and it is used by the part of the code generator that does classification of a specific global. The ExplicitSection disappears. It is moved onto MCSection as a new "IsDirective" bit. Since the Name of a section is either a section or directive, it makes sense to keep this bit in MCSection. Ultimately the creator of MCSection should canonicalize (e.g.) .text to whatever the actual section is. llvm-svn: 77803
