[PATCH] D104579: [SampleFDO] Add Pass1 of MIRAddFSDiscriminatorsPass before Block-Placement

[Rong Xu via Phabricator via llvm-commits]

xur added a comment.

This might just be specific to our deployment. Our AFDO optimized build
uses the profile generated in the previous release.
If we hold this Pass1 discriminator change and commit together with the FS
profile change. We won't see the FSAFDO performance in the release right
after -- we need to wait for another release to get all the samples with
Pass1 discriminations.
