; This test triggered a bug in the vector splitting where the type legalizer
; attempted to extract the element with by storing the vector, then reading
; an element back. However, the address calculation was:
; Base + Index * (EltSizeInBits / 8)
; and EltSizeInBits was 1. This caused the index to be forgotten.
