I think that mirroring/cloning (part of) the current buffer in a special
search buffer would be the cheapest solution.  The search buffer would
contain the normalized text, be built only when normalization is
needed and be rebuilt whenever a search option or the buffer text
changes.  I don't know whether `buffer-swap-text' could be used here.
