Pete Cooper f52123b454 [AArch64] Fix sext/zext folding in address arithmetic. ...

We were accidentally folding a sign/zero extend in to address arithmetic in a different BB when the extend wasn't available there.

Cross BB fast-isel isn't safe, so restrict this to only when the extend is in the same BB as the use.
