An edge from a call expression to the exit block is only an abnormal edge
if *none* of the successors of the call expression is the exit block.
This matters when a call of bool type is the condition of (say) a while
loop in a function with no statements after the loop. This *can* happen
in C, but it's much more common in C++ because of overloaded operators.
Suppresses some substantial number of spurious -Wmissing-noreturn warnings.
