fix various warnings in compilerplugins

These are triggered when using llvm-config --cxxflags for building,
and sometimes there's -Werror. The warnings were mostly unused
variables because of being used only in assert(), or default case
in switch that covers all enums (it's better to not handle default
to get warning if a case is not handled).
