c4228816 - [SelectionDAGBuilder] Use address width when lowering ptrtoaddr

[SelectionDAGBuilder] Use address width when lowering ptrtoaddr Instead of just deferring to ptrtoint, we should truncate to the index width and then perform the ZextOrTrunc. This is effectively NFC since ptrtoint ends up doing the same thing, but handling it explicitly is cleaner and will make it easier to eventually upstream the changes needed for CHERI support.
