This patch is motivated by (and factored out from) https://reviews.llvm.org/D66121 which is a debug info bugfix. Starting with DWARF 5 all Objective-C methods are nested inside their containing type, and that patch implements this for synthesized Objective-C properties. 1. SemaObjCProperty populates a list of synthesized accessors that may need to inserted into an ObjCImplDecl. 2. SemaDeclObjC::ActOnEnd inserts forward-declarations for all accessors for which no override was provided into their ObjCImplDecl. This patch does *not* synthesize AST function *bodies*. Moving that code from the static analyzer into Sema may be a good idea though. 3. Places that expect all methods to have bodies have been updated. I did not update the static analyzer's inliner for synthesized properties to point back to the property declaration (see test/Analysis/Inputs/expected-plists/nullability-notes.m.plist), which I believed to be more bug than a feature.
