c++: Include -Woverloaded-virtual in -Wall [PR87729]
This seems like a good warning to have in -Wall, as requested. But as
pointed out in PR20423, some users want a warning only when a derived
function doesn't override any base function. So let's put that lesser
version in -Wall (and -Woverloaded-virtual=1) while leaving the semantics
for the existing option the same.
