Mengxuan Cai eda3c93486 [LoopFuse] Ensure loops are in loop simplified form under new PM ...

Loop Fusion (Function Pass) requires loops in simplified form. With
legacy-pm, loop-simplify pass is added as a dependency for loop-fusion.
But the new pass manager does not always ensure this format. This patch
tries to invoke simplifyLoop() on loops that are not in simplified form
only for new PM.
