f019e44e74 verificsva: Support the followed-by operator in cover mode 
The implementation for the implication operator in cover mode actually
implements the followed-by operator, so we can re-use it unchanged.

It is not always the correct behavior for the implication operator in
cover mode, but a) it will only cause false positives not miss anything
so if the behavior is unexpected it will be visible in the produced
traces, b) it is unlikely to make a difference for most properties one
would practically use in cover mode, c) at least one other widely used
SVA implementations behaves the same way and d) it's not clear whether
we can fix this without rewriting most of verificsva.cc
