Subtarget's minimum/maximum occupancy, in number of waves per EU, that can be achieved when the only function running on a CU is F, each workgroup uses LDSSize bytes of LDS, and each wave uses NumSGPRs SGPRs and NumVGPRs VGPRs.

The flat workgroup sizes associated to the function are a range, so this returns a range as well.

Note that occupancy can be affected by the scratch allocation as well, but we do not have enough information to compute it.
