Adding energy_model instrument.

Browse Source 
This instrument can be used to generate an energy model for a device
based on collected power and performance measurments. The instrument
produces a C file with an energy model and an accompanying HTML report.

This instrument is very different from other instrumentation, as it
actually generates the run queue on the fly based on the operating
frequencies and idle states it discovers on the device. The agenda needs
only to contain the single "base" spec that defines the workload to be
used for performance measurement.

These are the traditional power-performance curves for the single-core runs.

<h3>CPUs Power Plot</h3>
Each line correspond to the cluster running at a different OPP. Each
point corresponds to the average power with a certain number of CPUs
executing. To get the contribution of the cluster we have to extend the
lines on the left (what it would be the average power of just the cluster).
