This seems to have broken all our microbenchmarks?

Emmanuel's out this week. Running dart bin/run.dart -t microbenchmarks locally seems to be doing reasonable things. The devicelab logs seem reasonable too.

@godofredoc may have ideas?

I'm going to try reverting this to see if it fixes the problem.

Can't revert cleanly.

why are we removing the origin checking? this will make things like flutter logs display old logs.

this may be the cause of the regression, in fact...

since @blasten is out, @zanderso can you look at this? I'm worried that we're missing many many days of microbenchmark data and could be missing any number of regressions.
