which is the middle-end. This is an oddity compared to other
-Wunused-* warnings. Moreover, Fortran has its own definition of
-Wunused-parameter that conflicts with the middle-end definition.
This patch moves the middle-end part of Wunused-parameter to the C/C++
FEs. I'm not sure if other FEs expected this warning to work. If so,
they do not seem to test for it. Ada, for example, explicitly disables
it.
