This one is nice, yes! We get coverage for anyone with plugin support.

All three of these, though, please leave as they were. They're either
needlessly noisy for COMPILE_TEST (GCC_PLUGIN_CYC_COMPLEXITY and
*_VERBOSE), or reduce the COMPILE_TEST coverage
(GCC_PLUGIN_RANDSTRUCT_PERFORMANCE).
(And perhaps a comment is needed to explain these to avoid confusion
in the future?)
