If a loop is removed (because of unrolling) then the loop dependence tracking introduced in dotnet#55936 and dotnet#56184 may not properly update. So when a loop is removed, walk up the chain of parent loops looking for one that is not removed, and record the dependence on that parent. Addresses last part of dotnet#54118.

Looks like the runtime-dev-innerloop completed ok but the step to report results hit an error: so will ignore. |
