      Description

      General primitive array equality/comparison/mismatch was intrinsified on x86 via JDK-8143355.

      A _vectorizedMismatch stub routine was added that is wired up in C2. The same stub routine can also be wired up in C1.

      For an example of how to wire up a stub routine in the interpreter and C1 see the fix for x86 CRC32 intrinsics:
