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?

2013-05-21  Jakub Jelinek  <jakub@redhat.com>

	PR tree-optimization/57331
	* 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.

Ok.  Sorry for the breakage.
