This commit attaches teaches ASTDeclReader::attachPreviousDecl to successfully merge two Decl's when one contains an inheritable attribute like the MSInheritanceAttr. Usually, attributes that are needed to present along the redeclaration chain are attached during ASTReading from ASTDeclReader::attachPreviousDecl, but no such thing is done for inheritable attributes. Currently, only the logic for merging MSInheritanceAttr is provided.
