We want the generice StdLibraryFunctionsChecker to report only if there
are no specific checkers that would handle the argument constraint for a
function.

Note, the assumptions are still evaluated, even if the arguement
constraint checker is set to not report. This means that the assumptions
made in the generic StdLibraryFunctionsChecker should be an
over-approximation of the assumptions made in the specific checkers. But
most importantly, the assumptions should not contradict.
