PR tree-optimization/92765 - wrong code for strcmp of a union member
gcc/ChangeLog:
PR tree-optimization/92765
* gimple-fold.c (get_range_strlen_tree): Handle MEM_REF and PARM_DECL.
* tree-ssa-strlen.c (compute_string_length): Remove.
(determine_min_objsize): Remove.
(get_len_or_size): Add an argument. Call get_range_strlen_dynamic.
Avoid using type size as the upper bound on string length.

handle_builtin_string_cmp.
