e5935fd52f3215c61831ecda2075c197b55a85f2 [LICM&MSSA] Limit store hoisting.
Summary:
If there is no clobbering access for a store inside the loop, that store
can only be hoisted if there are no interfearing loads.
A more general verification introduced here: there are no loads that are
not optimized to an access outside the loop.
Addresses PR40586.
