Minor changes for compatibility.
Cannot currently run these tests effectively:
1. One of the bench runs doesn't work on Py3 yet. is_types.py fails
with:
```
Traceback (most recent call last):
File "bench.py", line 91, in <module>
exec(open(args[0], 'r').read())
File "<string>", line 16, in <module>
AttributeError: module 'types' has no attribute 'InstanceType'
```
The test fundamentally depends on checking if a type is an instance
as part of what's being timed; the problem is types.InstanceType
was only meaningful for old-style classes where all instances have
the same type. Since that can't happen in Python 3 with new-style
classes only, types.InstanceType has been removed entirely. Is
it worth trying to figure out how to rejigger the test?
2. The calibrarions on the timings configs are horribly wrong for the
local machine (10x too small), but not sure what to calibrate them for.
3. The calibration algorithm sometimes goes off base. The objective
is to converge on something just under 10 seconds, and hit it three
times in a row. In this snippet #25 got close, then we keep iterating
and get further away in #27, #29, #31, #33 (this particular calibration
eventually hit it's three with runs #55-57.
```
run 25: 9.207: TARGET_COUNT=1019
run 26: 11.026: TARGET_COUNT=1106
run 27: 8.630: TARGET_COUNT=1003
run 28: 12.046: TARGET_COUNT=1162
run 29: 8.240: TARGET_COUNT=964
run 30: 12.062: TARGET_COUNT=1169
run 31: 8.232: TARGET_COUNT=969
run 32: 12.470: TARGET_COUNT=1177
run 33: 8.185: TARGET_COUNT=943
```
4. Running any of the timings fails with stdout mismatch, as there is
(unexpected?) timing output. Example CPPPATH - see the second line
of the captured output for the extra data. Is this new data emitted
by debug=time that the timings code is not expecting?
```

5. CPPPATH timing config runs into a command-line length problem if
calibrating. Might be a testcase for using a file for long command
lines even in the gcc case?
