[MachineLICM] Re-enable hoisting of constant stores This patch fixes an issue exposed on the SystemZ build bots when committing https://reviews.llvm.org/rL327856. The hoisting was temporarily disabled with an option. This patch now re-enables hoisting and checks that we only hoist a store instruction when all its operands are either constant caller preserved registers or immediates.
