[PATCH] D62700: [PGO] Handle cases of non-instrument BBs

[Rong Xu via Phabricator via llvm-commits]

xur updated this revision to Diff 202748.
xur added a comment.

My previous patch was not complete -- we need to set the profile count to the fail-to-instrument edge. Otherwise, we cannot propagate the counts in the CFG.
The new patch has this part of change.
Updated the test to test the profile-use.

Also added comments suggested by David.
