This reverts #54186 and adds new test cases.
While working on related stuff, I noticed that this improvement of mine was terrible and that it regressed some cases that were working before. The perf improvement was still there, just for a subset of possible cases. I now explored how this whole intra expression inference works and have much better understanding of the overall algorithm. I have some ideas how to deduplicate some work here but I will do that in a follow up PR. For the time being, it's much more important to land this revert that fixes some regressions.
