  Changed paths:
    M clang/lib/AST/DeclObjC.cpp

  Log Message:
  -----------
  ObjCMethodDecl::findPropertyDecl  - fix static analyzer null dereference warnings. NFCI.

All paths dereference the ClassDecl pointer, so use a cast<> instead of dyn_cast<>, assert that its not null and remove the remaining null tests.
