Subject: Add support for Neon VEXT (vector extract) shuffles. This is derived
 from a patch by Anton Korzh.  I modified it to recognize the VEXT shuffles
 during legalization and lower them to a target-specific DAG node.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79428 91177308-0d34-0410-b5e6-96231b3b80d8
