I committed the autofdo bootstrap and testing patches now. I did some small changes to the patchkit, so I'm reposting the final committed version:
- Addressed Jeff's comments - Fixed the grep code in the scripts - Unsupported tooling is now reported as unsupported - Unified tree bootstrap is tested and works - I fixed some problems I added to the TCL code for testing, now all the profiling test cases run again. Currently there are some new failures with autofdo available due to differences to the instrumented bootstrap; I'll address those separately. -Andi
