  [OpenMP] Introduce aligned synchronization into the new device RT

We will later use the fact that a barrier is aligned to reason about

Exiting a data environment will reset all values, it is wrong to adjust
them afterwards.

When we strip and accumulate constant offsets we need to pick the right
address space such that the offset APInt has the right bit width.
