[PATCH] D22021: AMDGPU/SI: Don't handle a loop if there is no loop at all for a terminator BB.

[Matt Arsenault via llvm-commits]

arsenm added a comment.

The comments I think are copied from another test and probably not relevant for this, so should be removed.

The test function should also have a better name about the situation with unreachables
