Eric Li 45643cfcc1 [clang][dataflow] Centralize expression skipping logic
A follow-up to 62b2a47 to centralize the logic that skips expressions
that the CFG does not emit. This allows client code to avoid
sprinkling this logic everywhere.

Add redirects in the transfer function to similarly skip such
expressions by forwarding the visit to the sub-expression.
