[AMDGPU] Limit register pressure of pipelined loops

Opt AMDGPU into the generic MachinePipeliner register-pressure detector via
shouldLimitRegPressure(), and supply an occupancy-aware verdict in
isScheduleRegPressureTooHigh(): reject a schedule whose SGPR or VGPR/AGPR
pressure would drop the kernel below its target occupancy, or exceed a
register class's addressability cap. On gfx90a+ VGPRs and AGPRs share one
register file, so their combined footprint is bounded together. These match
the limits GCNSchedStrategy enforces.
