de95c1b88b 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.

c1d287b4b7 Create a new ARM-specific DAG node, VDUP, to represent a splat from a

of trying to recognize the pattern during selection.

0ce3710825 During legalization, change Neon vdup_lane operations from shuffles to 
target-specific VDUPLANE nodes.  This allows the subreg handling for the
quad-register version to be done easily with Pats in the .td file, instead
of with custom code in ARMISelDAGToDAG.cpp.

b0abb4dc42 Use vAny type to get rid of Neon intrinsics that differed only in whether 
the overloaded vector types allowed floating-point or integer vector elements.
Most of these operations actually depend on the element type, so bitcasting
was not an option.

If you include the vpadd intrinsics that I updated earlier, this gets rid
of 20 intrinsics.

64efd90f8c Implement Neon VTRN instructions. For now, anyway, these are selected

convenient to have a custom DAG node for using these to implement shuffles,
we can add that later.
