Workaround attribute ordering issue with kernel only attributes
Placing the attribute after the kernel keyword would incorrectly reject the attribute, so use the smae workaround that other kernel only attributes use. Also add a FIXME because there are two different phrasings now for the same error, althoug amdgpu_num_[sv]gpr uses a consistent one. llvm-svn: 223490
