; Make sure that array alloca loaded and stored as multi-element aggregates are handled correctly
; Strictly the promote-alloca pass shouldn't have to deal with this case as it is non-canonical, but
; the pass should handle it gracefully if it is
; The checks look for lines that previously caused issues in PromoteAlloca (non-canonical). Opt
; should now leave these unchanged
