9783 * gimple-fold.c (get_range_strlen_tree): Record if the computed
9784 length is optimistic. If it is, then arrange to compute the
9785 conservative length as well.
9787 * gimple-fold.h (get_range_strlen): Update prototype.
9788 * builtins.c (check_access): Update call to get_range_strlen to use
9789 c_strlen_data pointer. Change various variable accesses to instead
9790 pull data from the c_strlen_data structure.

9794 minimum length if maximum lengh is unknown.

9796 that used c_strlen, it's no longer needed. Restructure slightly.
