The assertion previously did not work correctly because the operand was being truncated to an `int` prior to comparison. Change the assertion into a a reported error as suggested in https://github.com/llvm/llvm-project/pull/101840#issuecomment-2304992425 by @arsenm Finally, fix the lowering on 64-bit targets so that offsets larger than 32-bit are correctly addressed and add tests for various reported issues.
