RFA: Fix plugins/44459 1/2

I have divided the patch set for this PR into two parts to allow separate
review:
This one, the first part, changes only gcc-plugin.h ; the purpose of this
file is quite obviously to provide a part of the plugin interface.
Bootstrapped and regression tested in 160389 with --enable-build-with-cxx
This patch by itself allows testsuite/gcc.dg/plugin/one_time_plugin.c to
be compiled with gcc into a functioning gcc plugin.
I would consider this patch alone a possible fix for PR 44459, although I'd
prefer to have more functionality supported, as would be available by
combining
both parts of this patch set, or this part with a modified second part.
