re PR middle-end/23484 (__builtin___memcpy_chk miscompilation)
PR middle-end/23484
* builtins.c (fold_builtin_memory_chk, fold_builtin_stxcpy_chk,
fold_builtin_strncpy_chk, fold_builtin_snprintf_chk): If len is
not constant, but maxlen is, don't set len to maxlen, rather
set maxlen to len if len is a constant.
* gcc.c-torture/execute/builtins/pr23484-chk.c: New test.
* gcc.c-torture/execute/builtins/pr23484-chk-lib.c: New file.
