I don't think I know what you mean, here.  I don't see it as being at
all trivial, but maybe I'm missing something.
isearch-lazy-highlight-new-loop will need to get a list of regions to
skip, and pass this on to i-l-h-update which will need to step gingerly
through the allowed regions.

We should be able to take the list of boundaries from the bit of code
which searches for them in the first place.  Maybe.  Somehow.
