Merge vec_step and vec_align binaries into a new vectors binary (#926)

* Merge vec_step and vec_align binaries into a new vectors binary

This change just merges the two suites to reuse common functions
and definitions. There is probably room for further code consolidation
but probably best done as a separate change.

Contributes to #683
