Richard Diamond 4bf015c035 [AlignmentFromAssumptions] Fix a SCEV assertion resulting from address space differences. ... Summary: On targets with different pointer sizes, -alignment-from-assumptions could attempt to create SCEV expressions which use different effective SCEV types. The provided test illustrates the issue. In `getNewAlignment`, AASCEV would be the (only) alloca, which would have an effective SCEV type of i32. But PtrSCEV, the GEP in this case, due to being in the flat/default address space, will have an effective SCEV of i64. This patch resolves the issue by truncating PtrSCEV to AASCEV's effective type.
