AMDGPU: Don't add emergency stack slot if all spills are SGPR->VGPR This should avoid reporting any stack needs to be allocated in the case where no stack is truly used. An unused stack slot is still left around in other cases where there are real stack objects but no spilling occurs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@295891 91177308-0d34-0410-b5e6-96231b3b80d8
