  [AMDGPU] Add synthetic apertures and use them for barriers

Define what a synthetic aperture is, and adjust the barrier AS
to use this new system. This makes the barrier AS even safer to
use as now we can use all 32 bits of it without ever risking
hitting a valid address of any kind (LDS or outside LDS).
