; Show that we know how to translate vshl and vshr with immediate shift amounts.
; We abuse sign extension of vectors of i1 because that's the only way to force
; Subzero to emit these instructions.
; NOTE: We use -O2 to get rid of memory stores.
; REQUIRES: allow_dump
; Compile using standalone assembler.
