26633 (get_range_strlen): Accept c_strlen_data pointer for external
26634 call sites as well. Pass through to call to internal get_range_strlen.
26635 Adjust minlen, maxlen and maxbound as needed.
26636 (get_maxval_strlen): Update comments.
26637 (gimple_fold_builtin_strlen): Update call to get_range_strlen
26638 to use c_strlen_data pointer. Change variable accesses to instead
26639 use c_strlen_data data members.
26641 * gimple-fold.c (get_range_strlen): Update prototype.
26642 (get_range_strlen_tree): Update prototype. Drop minlen/maxlen
26643 local variables. Use pdata to return information to caller.

26645 (get_range_strlen -- static version): Similarly.
26646 (get_range_strlen -- extern version): Update for internal
26647 get_range_strlen API change. Convert to external data format.
