Log:
    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.
