[PATCH] D102830: [AMDGPU] Avoid null export insertion when unifying exit blocks

[Ruiling, Song via Phabricator via llvm-commits]

Hi, I think we can further simplify the logic in our backend regarding export done and implement my idea as D105610 <https://reviews.llvm.org/D105610>, could you take a look if you have concern? the main idea is we just trust frontend will setup exp done correctly and **only** insert exp-null-done for kill intrinsic which is handled in SILateBranchLowering.cpp.
