[MAGEEC] [BEEBS] Removal of measure.exp (introducing mageec-wand.exp)

I have just pushed a series of commits that rework the dejagnu support
within BEEBS.  The most noticeable change is that measure.exp is gone,
and replaced by mageec-wand.exp.  The reason for this is simply that
"measure" is too generic a name, the new name reflects the tool being
used to perform the measurement.  Other than the name change, use of
the new script should be exactly as it was with measure.exp.

[ For now the new mageec-wand.exp script still uses the energytool.py
script that ships with BEEBS, I posted another mail to the mailing
list about this. ]

The new dejagnu support makes use of a library of functions within
beebs/lib/beebs.exp, to help run the tests.  The basic idea is that
there's a defined process for running the benchmarks within the
support library, each script, like mageec-wand.exp, just overrides
those functions within the library that it needs in order to perform
its task.

Along with mageec-wand.exp I have added perf-stat.exp, this use the
Linux perf tool which is available for x86-64 (and some other
architectures), to gather things like instruction counts.

There is also run.exp which just runs the benchmarks.

All feedback welcome, let me know if there are any problems.
