Pass correct type to irange::contains_p() in ipa-cp.cc.
There is a call to contains_p() in ipa-cp.cc which passes incompatible types. This currently works because deep in the call chain, the legacy code uses tree_int_cst_lt which performs the operation with widest_int. With the upcoming removal of legacy, contains_p() will be stricter. gcc/ChangeLog: * ipa-cp.cc (ipa_range_contains_p): New. (decide_whether_version_node): Use it.
