Auto merge of #110705 - saethlin:ignore-locals-cost, r=cjgillot
Remove the size of locals heuristic in MIR inlining This heuristic doesn't necessarily correlate to complexity of the MIR Body. In particular, a lot of straight-line code in MIR tends to never reuse a local, even though any optimizer would effectively reuse the storage or just put everything in registers. So it doesn't even necessarily make sense that this would be a stack size heuristic. So... what happens if we just delete the heuristic? The benchmark suite improves significantly. Less heuristics better? r? `@cjgillot`
