Can you explain what the problem is ? This patch doesn't seems to do much more than moving the check for the value to be a load from within InstCombineLoadStoreAlloca to FindAvailableLoadedValue via an out parameter (which seems like an hidden dependency, I'm not super fan TBH).

What do I miss here ?
