Just perform an early return instead of this `continue` -- if the bug report is
marked as invalid, then I don't think that anything else matters.
By the way, this also applies to the `markInvalid()` calls that are within
`MallocBugVisitor::VisitNode`. (You didn't touch that part of the code, but
consider inserting some early returns there as well to highlight that the
remaining 150+ lines of the method are irrelevant in that case.)
