[PATCH] Fix simplify_cond_using_ranges ICE (PR tree-optimization/57331)

[Jakub Jelinek]

Hi!

int_fits_type_p ICEs if the second argument is pointer type (those don't
have TYPE_MIN_VALUE/TYPE_MAX_VALUE).  Fixed thusly, bootstrapped/regtested
on x86_64-linux and i686-linux, ok for trunk?

        * tree-vrp.c (simplify_cond_using_ranges): Don't optimize
        comparison of conversion from pointer type to integral type
        with integer.

        * gcc.c-torture/compile/pr57331.c: New test.
