re PR tree-optimization/59860 (ICE in compute_may_aliases, at tree-ssa-structalias.c:6843)
PR middle-end/59860
* tree.h (fold_builtin_strcat): New prototype.
* builtins.c (fold_builtin_strcat): No longer static. Add len
argument, if non-NULL, don't call c_strlen. Optimize
directly into __builtin_memcpy instead of __builtin_strcpy.
(fold_builtin_2): Adjust fold_builtin_strcat caller.
* gimple-fold.c (gimple_fold_builtin): Handle BUILT_IN_STRCAT.
