This is the first step towards refactoring the x86 vector shuffle code. The

general idea here is to have a group of x86 target specific nodes which are
going to be selected during lowering and then directly matched in isel.

The commit includes the addition of those specific nodes and a *bunch* of
patterns, and incrementally we're going to switch between them and what we
have right now. Both the patterns and target specific nodes can change as
we move forward with this work.
