  [Clang] Fix ClassifyImplicitMemberAccess to handle cases where the access in an unevaluated context is not within a CXXRecordDecl or CXXMethodDecl

ClassifyImplicitMemberAccess assumes that if we are not in a static context then
the DeclContext must be a CXXRecordDecl or a CXXMethodDecl. In the case of the
unevaluated context this may not be true.

This will lead to a crash because contextClass will remain a nullptr.
