Limit ranger query in ipa-prop.cc to integrals.

ipa-* still works on legacy value_range's which only support
integrals.  This patch limits the query to integrals, as to not get a
floating point range that can't exist in an irange.

gcc/ChangeLog:

	* ipa-prop.cc (ipa_compute_jump_functions_for_edge): Limit ranger
	query to integrals.
