re PR c++/36921 (warning "comparison does not have mathematical meaning" is not correct for overloaded operators that do not return boolean)

PR c++/36921
* c-common.c (warn_about_parentheses): Remove ARG_UNUSED from
arg_left.  Don't warn about X<=Y<=Z if comparison's type isn't
integral.

* g++.dg/warn/pr36921.C: New.
