git branch: fix performance problem
'git branch' looks at _all_ the refs, and verifies them. Which means that
during cold-cache situations with a slow disk (and lots of tags, for
example) it can take several very annoying seconds (7.5s according to a
report by Carlos R. Mafra).
This avoids most of it by simply doing the filtering before looking up
the commits, by using the "raw" version of for_each_ref.
