JIT: refactor CSE to allow running greedy ML heuristic in release #98729
Conversation
Revise things a bit so that we can run the greedy ML heuristic in release mode, with a built-in set of "good" parameters. These parameters come from a policy gradient run over a 200 method training set, on the asp.net windows x64 collection. Contributes to dotnet#92915.

@EgorBo PTAL This will be a bit painful to review as I moved a bunch of methods to a new intermediate class, and in doing so physically moved them in the file. For the most part things did not change (much). The baked-in parameters may or may not be any good. We'll see. I will push an interim change to enable it by default. |

Looking 👀 |
Actually I'm going to hold off; let's get this bit merged and then I will put up a draft PR to flip it on by default. |

As far as I can follow your changes, they look reasonable to me, LGTM!
Are the diffs huge? 🙂 |
The code size diffs don't look very good right now. One of the things I need to figure out is how to make sure that the secondary objectives don't get too crazy. |

This is a no diff change so failures above are unrelated. |
