[PATCH] D16561: Tweak unnamed label syntax in textual IR for easier matching in tests.

[Evgeniy Stepanov via llvm-commits]

eugenis created this revision.
eugenis added subscribers: llvm-commits, pcc.
eugenis set the repository for this revision to rL LLVM.

Change the unnamed label comments like
  ; <label>:8  ; preds = %1
to
  ; <label>:8:  ; preds = %1

This way lit tests can match [[LABEL]]: in both asserts and no-asserts builds.
