Two new kinds are introduced - 'instrumented-build' and 'generate-profile'. The instrumented-build kind is almost identical to the build kind, except it can be used earlier in the task graph. The 3-tier PGO process becomes: instrumented-build -> generate-profile -> build The final build stage is identical to any other build, except it has the 'use-pgo' flag set to True in its task definition. This flag causes the transforms to add the instrumented-build and generate-profile tasks to the taskgraph.
