[PATCH] D64819: [UpdateTestChecks][Bug41532] Add handle of basic block names.

[Whitney via Phabricator via llvm-commits]

Whitney added a comment.

I cannot think of any clean way to identify labels, there are three ways that label can be:

1. at the start of a basic block.
2. follow by "label".
3. incoming blocks in phinode.

@MaskRay Do you feel strong to limit the change only to label? If so, can you give me some guidance on how to do it?
