We use getCurrentCounter() in one spot where there isn't guaranteed to be an active region: the `else' part of an IfExpr in a TopLevelCodeDecl. Fix this issue by assigning a pseudo-counter to the `else' part when the region stack is empty. This patch also adds crash tests which cover other code paths which rely on getCurrentCounter() when handling TopLevelCodeDecls. Fixes SR-4453.
