This patch replaces VPWidenRecipe with VPInstructions. This is still WIP
and needs to handle a few additional cases, but I wanted to share this
early to make sure the direction makes sense.

With the current version, we get

  Expected Passes    : 286
  Unexpected Failures: 63

I introduced a new VPWidenInstruction, but maybe it would be better to
just use VPInstruction.

If the direction looks right, I'll also continue with other recipes.
