ObjC Class Property: don't emit class properties on old deployment targets. For old deployment targets, emit nil for all class property lists. rdar://25616128 llvm-svn: 266800

Class Property: generate metadata for class properties in categories. The list of class properties is saved in Old ABI: category->class_properties (category->size will be updated as well) New ABI: category->class_properties (a flag in objc_image_info to indicate whether or not the list of class properties is present) rdar://23891898 llvm-svn: 259267

[CodeGen][ObjC] Remove the leading `l_` from ObjC symbols and make private symbols in the __DATA segment internal. This prevents the linker from removing the symbol names. Keeping the symbols visible enables tools to collect various information about the symbols, for example, tools that discover whether or not a symbol gets dirtied. rdar://problem/48887111 Differential Revision: https://reviews.llvm.org/D61454 llvm-svn: 360359
