[PATCH 06/11] perf: dereference to a commit when building

[Thomas Rast <trast@student.ethz.ch>]

So far the automatic compilation in 'run' just ran rev-parse on the
user input.  This means the user could test once for v1.7.9 and once
for 828ea97 (Git 1.7.9, 2012-01-27) and the script would never realize
that they are actually the same.  Even more confusingly, the user
could test 828ea97d and ask about './aggregate.perl v1.7.9' and it
would not find any results.

Dereference to a commit when constructing the directory name to avoid
this.
