[AMDGPU] Make temp vgpr selection stable in indirectCopyToAGPR

[rampitec]

Summary

This uses rotating reminder of division by 3 to select another
temp vgpr each next time in a sequence of several agpr copies.
Therefore, temp vgpr selection depends on the generated agpr
number. This number could change with any unrelated change to
the register definitions.

Stabilize the selection by using a real agpr number.

Thanks! This also cropped up in D119552.

Unrelated to this patch; The highest VGPR register number should be shifted back to the lowest free register.
Was there any follow-up patch planned?

We need to see - for this testcase, the code which handles the finding and reserving lowest available free register will be hit or not. If the nature of this testcase is like that we won't hit that part of the code, then this is indeed the expected behavior. Otherwise, there is an unhandled bug in the patch https://reviews.llvm.org/D123525 which need to be fixed.

   // Ideally we want to have three registers for a long reg_sequence copy
   // to hide 2 waitstates between v_mov_b32 and accvgpr_write.
   unsigned MaxVGPRs = RI.getRegPressureLimit(&AMDGPU::VGPR_32RegClass,
                                              *MBB.getParent());
 
   // Registers in the sequence are allocated contiguously so we can just
   // use register number to pick one of three round-robin temps.
-  unsigned RegNo = DestReg % 3;
+  unsigned RegNo = (DestReg - AMDGPU::AGPR0) % 3;
   Register Tmp =
       MBB.getParent()->getInfo<SIMachineFunctionInfo>()->getVGPRForAGPRCopy();
   assert(MBB.getParent()->getRegInfo().isReserved(Tmp) &&
          "VGPR used for an intermediate copy should have been reserved.");
 
   // Only loop through if there are any free registers left, otherwise
   // scavenger may report a fatal error without emergency spill slot
   // or spill with the slot.
