Reviewed by Dewei Zhu.

This patch adds signpost patches to Speedometer plans, which will allow us to annotate generated profiles (--profile).

Currently, for each iteration, two signposts are created: one overarching signpost called "${suite}.${test}" labeling the full subtest run, and "${suite}.${test}: warmup" labeling just the warmup section.
