[NeedForSpeed] Benchmarks, please

[Tim Peters]

All runs here on Windows XP Pro SP2, on Pentium 4 3.2 GHz w/ 1GB RAM.

pystone
-------
Each figure is best of 5 runs, with argument 200000 (4x the default).  The
figures for released Pythons come from the released python.org Windows
installers.

2.4.3   49510
2.5a1   48550.2
2.5a2   48345.3
trunk   49341.2  SVN revision is -r 46439 (cautious Windows inlining)

Inlining is delicate!  For contrast:

trunk-1 42853.5  with hyper-aggressive inlining enabled
trunk-2 46304.4  with all inlining disabled

pybench
-------
2.4.3 vs trunk revision 46439.  See attachment (my mailer would split the
lines, making it an unreadable mess).
