Go 1.9 and up write "pkg", "goos", and "goarch" keys in benchmark
output. benchstat now understands benchmark labels, and uses them to
separate incomparable benchmark results. cmd/benchstat gains a
command-line flag called "-split" to control this, defaulting to
"pkg,goos,goarch".

The Uploads table gets an entry when a user or the server aborts an
upload in mid-upload. The Records table is cleaned up by the
transaction, but the Uploads entry is left behind.

The optimized query that is used for the perf.golang.org homepage did
not properly exclude these uploads that have no records.

This makes the geomean undefined (or zero, depending on who you ask).
Since these usually come from counts, it's more informative to just
omit the benchmark.

of benchstat. This is fetched from the ViewURL provided by the storage

SortBy seems to sometimes sort by the second column instead of the
first. Until that bug is figured out, do the sorting one column at a
time to control the ordering.

Without this patch, try
/trend?q=upload%3A20170216.3+name%3ARegexpMatchEasy0_1K&raw=1
and
/trend?q=trend%3Abuild.golang.org%2Fwindows-amd64-gce+name%3AGzip+commit-time%3E2016-11-08+commit-time%3C2016-11-30&raw=1

The former seems to sort first by "commit" instead of "commit-time",
but the latter sorts by "commit-time" first. Apply the patch and both
are sorted by commit-time.
