Description
I just noticed that GCC has unordered comparison operators.
It might be more efficient to use those than implementing unordered operators manually here.

Research direction
Start in src/builder.rs around line 1307, then read GCC's unordered comparison operators in gcc/tree.def around lines 861-870. Compare the existing manual implementation with the GCC operators and verify that the generated comparisons preserve the intended behavior and improve efficiency; the work is done when the implementation uses the appropriate GCC operators.
