[VPlan] Handle equal address and store ops in onlyFirstLaneDemanded.

With opaque pointers, the stored value and address can be the same.

Previously the code in VPWidenMemoryInstructionRecipe::onlyFirstLaneDemanded
incorrectly considers stores with matching store and pointer operands as
only demanding the first lane, causing a crash.
