cc @dotnet/jit-contrib, @AndyAyersMS PTAL. Diffs show some churn in LSRA/layout, though I also noticed locally that this also affects weighted score computations in CSE/physical promotion/etc. Thanks! |

Follow-up to #112499. By ensuring OSR method entry blocks' weights match
fgCalledCountduring entry canonicalization, we can guarantee that later runs of profile synthesis won't modifyfgCalledCount. This should unblock #111915 (comment).
