`case-fold-search' variable (i.e., f matches F). This only
removes the code that was added to ensure that f also matched
all chars that F matched. For instance, after this commit, f
no longer matches 𝔽.
This was necessary because the logic created a regexp with
2^(length of the string) redundant paths. So, when a very
long string "almost" matched, Emacs took a very long time to
figure out that it didn't. This became particularly relevant
because isearch's lazy-highlight does a search bounded by (1-
match-end) (which, in most circumstances, is a search that
almost matches). A recipe for this can be found in bug#22090.
