  [LoopVectorize][Fix] Crash when invariant store address is calculated inside loop

Fixes #57572

Generally LICM pass is responsible for sinking out code that calculates
invariant address inside loop as it only needed to be calculated once.
But in rare case it does not happen we will not be vectorizing the
loop.
