Support all conditions in predicated vectorization

Support all condition types inside the condition when performing
diamond loop auto-vectorization. This allows diamond loop
auto-vectorization to be performed on a greater variety of loops.

To support this change, new vector condition nodes are added to
mirror the scalar condition nodes.

Also add a new gtest class to test whether predicated vectorization
can be performed on different combinations of condition types and
data types.
