Stephan Bergmann 5d546de67b Adapt to Clang 12 trunk RecursiveASTVisitor change
<https://github.com/llvm/llvm-project/commit/
5689b38c6a4220cc5f6ba68a56486229b10071bf> "Removed a RecursiveASTVisitor feature
to visit operator kinds with different methods".

That change is incompatible in that before the change individual TraverseUnary*
and TraverseBin* functions were called, while now TraverseUnaryOperator and
TraverseBinaryOperator/TraverseCompoundAssignOperator are called for all the
different operators.  Fixed that with a few #if for the non-shared plugins, but
that doesn't work for the shared plugin.  So made the two affected plugins non-
shared for now and left a better fix as a TODO.
