[PATCH] D12067: AMDGPU: Refactor exp instructions

[Marek Olšák via llvm-commits]

Please ignore what I said. I've talked with a Catalyst guy and he said we should emit exports as late in the shader as possible. The export memory can be allocated in the first export instruction and it limits the number of waves that can be run from that point. It's okay to reorder exports, but please don't emit them too early.
