This change adds a pass to scalarize vectors in global scope into arrays. There are three distinct parts 1. find the globals that need to be updated and define what the new type should be 2. initialize that new type and copy over all the right attributes over from the old type. 3. Use the instruction visitor pattern to update the loads, stores, and geps for the layout of the new data structure. resolves https://github.com/llvm/llvm-project/issues/107920
