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.

Update comment to remove special case for vector extending loads. An
...
extending vector load should extend each element in the same way as the
corresponding scalar extending load.

When splitting a VAARG, remember its alignment.

This produces terrible but correct code.

add ISD::STACKADDR to get the current stack pointer. Will be used by sjlj EH
...
to update the jmpbuf in the presence of VLAs.

Followups: docs patch for the builtin and eh.sjlj.setjmp cleanup to match

...
into a separate header to allow clients to use them without pulling in
SelectionDAG-specific declarations.
