First pass performance try bot.

Piggy-backed a performance comparison mode onto the existing bisect architecture. The script will build and run the specified performance test, revert any local changes, build, and run again. At the moment, only chromium changes can be perf-tested. Future CL's will add the ability to perf test blink changes.

Waiting on http://codereview.chromium.org/27413002, http://codereview.chromium.org/26179009.

BUG=
TEST=

Modify run-perf-test.cfg, commit, and run git try --user=<user> -b linux_perf_bisect

Expect bot to run with/without patch, ie. http://build.chromium.org/p/tryserver.chromium/builders/linux_perf_bisect/builds/387
