I don't think this is doing anything.
If you look at the test run you can see that -fno-tree-strlen is never
passed (I think you actually mean -fno-optimize-strlen for that
matter).

I'm looking for a review of the patch below (beyond using
DEF_EXT_LIB_BUILTIN to declare the built-in rather than
DEF_LIB_BUILTIN, as already pointed out by Jakub):

The attached patch adds basic support for handling strnlen
as a built-in function. It touches the strlen pass where
it folds constant results of the function, and builtins.c
to add simple support for expanding strnlen calls with known
results. It also changes calls.c to detect excessive bounds
