[PATCH] D79498: [amdgpu] Fix check of VCC.

[Michael Liao via Phabricator via llvm-commits]

hliao added a comment.

One alternative is to check `isSuperRegisterEq(Reg, VCC)` for conciseness and readability. Not sure, we will have similar issues on other special registers with 16-bit subregs. But, I admit that's costy compared to the current `switch`.
