Make blend tests more specific
...
Following the lead set by r209324, I'm making these tests match the whole
instruction, so we can be sure we're lowering them correctly.

Added tests for shufflevector lowering to blend instrs.
...
These tests ensure that a change I will propose in clang works as
expected.
Summary:
Added tests for the generation of blend+immediate instructions from a
shufflevector.
These tests were proposed along with a patch that was dropped. I'm
committing the tests anyway to protect against possible regressions in
codegen.

The VPSHUFB 256-bit instruction may be generated when one of input vector is undefined or zeroinitializer.

I've added the "zeroinitializer" case in this patch.
