spirv: new vectorization helper

The old vectorization helper (WipElementWise) was clunky and a bit
annoying to use, and it wasn't really flexible enough.

This introduces a new vectorization helper, which uses Temporary and
Operation types to deduce a Vectorization to perform the operation
in a reasonably efficient manner. It removes the outer loop
required by WipElementWise so that implementations of AIR instructions
are cleaner. This helps with sanity when we start to introduce support
for composite integers.

airShift, convertToDirect, convertToIndirect, and normalize are initially
implemented using this new method.

```
