This will ensure that passes that add new global variables will create them in address space 1 once the passes have been updated to no longer default to the implicit address space zero. This also changes AutoUpgrade.cpp to add -G1 to the DataLayout if it wasn't already to present to ensure bitcode backwards compatibility.
