Fix dynamic-index insertelement in LongVectorLoweringPass - #1701

Conversation
In LongVectorLoweringPass::visitInsertElementInst for dynamic indices, only reuse a LoadInst's pointer operand when it is in the Private address space (avoiding writes into global or constant memory when the vector value was loaded from a buffer), and reload the modified array from PtrOperand after storing the inserted element instead of returning the unmodified pre-store value.
