If we try to eagerly process our skip count, we might see the end of the inner iterator. `Iterator::advance_by` is supposed to return a non-zero `Err` count when exhausted, but there's no room for `Skip` to report anything in this case. So, it's better that we don't even try.
Invalid lifetime suggested:

It does not have any use, and it is a no-op we have to process on the hot path of macro parsing.
The parsing code is much hotter than `compute_locs()`, so perform the match over there. This might mildly change the debug representation of computed `[MatcherLoc]`s, but it's probably worthwhile for perf.
