  -----------
  [AMDGPU] Fix handling of DBG_VALUE_LIST while fixing the dead frame indices. (#109685)

Both SGPR->VGPR and VGPR->AGPR spilling code give a fixup to the spill
frame indices referred in debug instructions so that they can be
entirely removed. The stack argument is present at 0th index in
DBG_VALUE and at 2nd index for DBG_VALUE_LIST.
