Time spent on the 20037 models both runs have. The last column counts only the 20034 that reached the same phase in both: a model that fails earlier stops paying for the phases it no longer reaches.

Caveats
- The baseline is the newest run of wasm-jit, not the commit the pull request is based on, so a difference can also come from something merged into wasm-jit since the pull request was branched.
