This CL refactors CaptureVars to use a visitor type so it's easier to break out helper functions to review. It also simplifies the quirks-mode handling of function literals: instead of trying to maintain information about whether we're inside a function literal or not, it now just rewrites the recorded position information for any newly added free variables after walking the function literal. (Quirks mode is only for "toolstash -cmp"-style binary output testing of normal code and will eventually be removed, so I don't think it's important that this is an O(N^2) algorithm for deeply nested function literals with lots of free variables.)
