61998afc56 Python: Remove unnecessary comment 
Was introduced in 5d031d7abe when I actually fixed
the loop variable capture problem.

321d5104f0 Python: CG trace: Autogenerate BytecodeExpr.qll 
Some code I had lying around, just hadn't comitted.

Not that useful since most of these have been disabled in 55404ae98 for now.

3ead2e3dc7 Python: CG trace: Improve performance by only logging when needed 
Seems like a 2x performance overall

wcwidth:
  - DEBUG=True 5.78 seconds
  - DEBUG=False 2.70 seconds

youtube-dl
  - DEBUG=True 238.90 seconds
  - DEBUG=False 120.70 seconds

fbd939133e Python: CG trace: More caching 
Improves runtime of tracing youtube-dl from 296.19 seconds to 224.50 seconds.

Better, but still not that amazing :|

As would normally be invoked by `python -m <module-name>` now works with
`cg-trace --module <module-name>`.

This is useful for tracing invocations of `pytest`.
