LLDB supports 32-bit versions debugging 64-bit hosts and vice versa, so we
need LLDB_INVALID_ADDRESS to remain the largest address-sized host we can
communicate with.  So LLDB_INVALID_ADDRESS needs to remain 64-bit
everywhere.

It looks like some progress was made on this already as I see we had a
swift-lldb pull request on this.

Thanks for looking into this!
