-Wtautological-overlap-compare is an opt-in warning added in clang 3.5. It warns about overlapping comparisons that are always true or false, such as:
if (x > 4 || x < 10) {} // warning! always true
int b = x < 2 && x > 5; // warning! always false
return x > 4 || x < 10; // warning! always true

There are currently no -Wtautological-overlap-compare warnings in mozilla-central.
