Fix #14. Cast signed strings to unsigned to prevent ctype.h warning
Split each benchmark into its own directory ... again.

Turns out that merging similar benchmarks into a single directory was
not a good idea.  This patch separates them again, but keeps the source
common.

All similar benchmarks now have different names, and the source lives in
a common central location, so, for example, we have benchmarks
`ctl-stack' and `ctl-vector', and the source for both lives in the `ctl'
directory.

ChangeLog:

	* configure.ac: Add split benchmarks to benchmark list.
	* configure: Regenerate.
	* src/ctl-stack/Makefile.am: New file.

Delete the analysis directory.

Following feedback on the mailing list it seems the contents of the
`beebs/analysis` directory are no longer required.

ChangeLog:

	* analysis/Makefile.am: Deleted.
	* analysis/Makefile.in: Deleted.
	* analysis/all_stats.py: Deleted.
	* analysis/cmd.arm-none-eabi: Deleted.
	* analysis/cmd.avr-unknown-none: Deleted.
	* analysis/instruction_stats.py: Deleted.
	* analysis/simulator.in: Deleted.
Update README.md.

Things have moved on in BEEBS, and the README has fallen behind.  This
should bring things up to date.

ChangeLog:

	* README.md: Update for latest state of BEEBS.

Update new dejagnu to handle newly split benchmarks.

Benchmarks are now split, so one binary per directory.  This commit
updates the dejagnu work to reflect this.

ChangeLog:

	* beebs.test/mageec-wand.exp (beebs_setup_before_benchmark_run):
	Rename to ...
	(beebs_setup_before_benchmark): ... this.
	(beebs_cleanup_after_benchmark_run): Rename to ...
	(beebs_cleanup_after_benchmark): ... this.
	(beebs_cleanup_after_benchmark_run): Update, use benchmark not
	filename to identify results.
	* beebs.test/perf-stat.exp (beebs_run_benchmark): Update
	parameters.  The filename is now a full path, use as such.  Use
	benchmark, not directory to identify results.
	* lib/beebs.exp (default_beebs_filter_benchmarks): Renamed to...
	(default_beebs_filter_benchmark): ...this. Rename parameters.
	(default_beebs_setup_before_benchmark): Add filename parameter.
	(default_beebs_cleanup_after_benchmark): Add filename parameter.

	(beebs_get_benchmark_files): Deleted.
	(default_beebs_announce): Remove directory parameter.
	(default_beebs_run_benchmark): Likewise.
	(beebs_run_all_benchmarks): Remove calls to deleted functions.
	Assume only one binary in each benchmark directory.  Update
	parameters on remaining calls.
	(beebs_restore_default_procs): Reorder procedures.  Update
	parameters.
