X Title: GH-90043: Handle NaNs in `COMPARE_OP_FLOAT_JUMP` by brandtbucher · Pull Request #100278 · python/cpython

Description: COMPARE_OP_FLOAT_JUMP contains two DEOPT_IF branches for NaN values. This means that COMPARE_OP will repeatedly specialize and deoptimize in the presence of NaNs. The current scheme can be slightly modified to handle unordered operands correctly, and remove these checks entirely. Issue: gh-90043
