demandimport: instrument python 2 code with trace events
This causes the evaluation of an import in Python 3 to emit some trace
data. There's some interesting wrinkles in here, like the fact that
before we even hit dispatch we've demand-imported `sys` several times,
despite the fact that `sys` was already fully loaded as one of the
first few statements in the `hg` script. I don't think that's actually
costing us a ton of performance, but it's probably something we should
investigate fixing some day.
