These are all emitted into a section with a cstring_literal attribute. The
attribute permits the linker to coalesce the string contents. The address of
the strings are not important.

These strings are constants, mark them as such. This doesn't matter too much in
practice on MachO since the constants are placed into a special section and not
referred to directly.

r251874 stopped back-patching the AST when an Objective-C 'readonly'
property is redeclared in a class extension as 'readwrite'. However,
it did not properly handle merging of Objective-C property attributes
(e.g., getter name, ownership, atomicity) to the redeclaration,
leading to bad metadata. Merge (and check!) those property attributes
so we get the right metadata and reasonable ASTs. Fixes
rdar://problem/23823989.

After, properties from class extensions no longer show up in
ObjCInterfaceDecl::properties(). Make ObjCCommonMac::EmitPropertyList()
explicitly look for properties in class extensions before looking at
direct properties.
Also add a test that passes both with clang before r251874 and after this
patch (but fails with r251874 and without this patch).
