Stephan Bergmann 067603dbda -Wunused-but-set-{parameter,variable} in CompilerTest_compilerplugins_clang
...new with Clang trunk 13.  As a rule of thumb, this change adds explicit
cast-to-void silencing in those .cxx that already contained other such silencing
casts and adds wholesale #pragma clang diagnostic ignored in all others.
