  AMDGPU: Fix allocating GDS globals to LDS offsets

These don't seem to be very well used or tested, but try to make the
behavior a bit more consistent with LDS globals.

I'm not sure what the definition for amdgpu-gds-size is supposed to
mean. For now I assumed it's allocating a static size at the beginning
of the allocation, and any known globals are allocated after it.
