      Description

      Hotspot crash on guarantee assertion trying to generate code with SIMD ld/st(1,2,3,4) instructions with sp register usage. According to specification, these instructions can be used from stack too. Seems like no hotspot code path is using such combination, so, this case wasn't found so far.
