tests/perf_bench: Add some miscellaneous performance benchmarks.

misc_aes.py and misc_mandel.py are adapted from sources in this repository.
misc_pystone.py is the standard Python pystone test.  misc_raytrace.py is
written from scratch.

# Pure Python AES encryption routines.
#
# AES is integer based and inplace so doesn't use the heap. It is therefore
# a good test of raw performance and correctness of the VM/runtime.
#
# The AES code comes first (code originates from a C version authored by D.P.George)
# and then the test harness at the bottom.
