Bug #1520864 (again): unpacking singleton tuples in list comprehensions and
...
generator expressions (x for x, in ... ) works again.
Sigh, I only fixed for loops the first time, not list comps and genexprs too.
I couldn't find any more unpacking cases where there is a similar bug lurking.
This code should be refactored to eliminate the duplication. I'm sure
the listcomp/genexpr code can be refactored. I'm not sure if the for loop
can re-use any of the same code though.
Will backport to 2.5 (the only place it matters).

Bug #1191458 : tracing over for loops now produces a line event
...
on each iteration. I'm not positive this is the best way to handle
this. I'm also not sure that there aren't other cases where
the lnotab is generated incorrectly. It would be great if people
that use pdb or tracing could test heavily.
Also:
* Remove dead/duplicated code that wasn't used/necessary
because we already handled the docstring prior to entering the loop.
* add some debugging code into the compiler (#if 0'd out).

- Add new Warning class, ImportWarning
...
- Warn-raise ImportWarning when importing would have picked up a directory
as package, if only it'd had an __init__.py. This swaps two tests (for
case-ness and __init__-ness), but case-test is not really more expensive,
and it's not in a speed-critical section.
- Test for the new warning by importing a common non-package directory on
sys.path: site-packages
- In regrtest.py, silence warnings generated by the build-environment
because Modules/ (which is added to sys.path for Setup-created modules)
has 'zlib' and '_ctypes' directories without __init__.py's.

Use macro versions instead of function versions when we already know the type.

This will hopefully get rid of some Coverity warnings, be a hint to
developers, and be marginally faster.
Some asserts were added when the type is currently known, but depends
on values from another function.
