c0374a95df Allow creating symbols in TF loops. This is on a best-effort basis, and only works in cases when the symbol being created doesn't depend on previous iterations. 
This change only adds the feature, but does not enable it yet. It will be enabled separately.

14c78f9675 Always convert function calls dynamically. This greatly simplifies the implementation at the cost of less readability of the output.

9628503d8e Handle variables defined in a single conditional branch. They will still not work in TensorFlow, but this is sometimes valid in pure Python code. The error for TensorFlow or misbehaving Python code will now happen at runtime rather than compile-time which allows for well-behaved Python to execute as expected.

bf6c9500be Use a logging mechanism that allows greater output control. 
Requirements that this mechanism meets:
 * users should be able to change the verbosity programmatically (ag.set_verbosity)
 * users should be able to change the verbosity without touching the code (AUTOGRAPH_VERBOSITY env variable)
 * different levels of verbosity should be supported, ala vlog
 * the mechanism should work in interactive prompts like Jupyter by mirroring the log messages to console
All these controls are global (at least for now).

b17d53c0cd Replace a few calls of Session run with evaluate 
In order to support tests running in eager mode we need to avoid
unnecessary use of Sessions in tests. This moves to remove some
of the uses of the `run` function in favor of `evaluate`.

402e5862fa Use the conversion options object throughout the process (including during the deferred runtime conversions), and remove its arg_types field. 
This is necessary for the correct behavior when converting dynamic functions - converted_call must operate in a manner consistent with the original parameters.

226cc7c47e Allow unsupported comparison operators to be passed through and scale back the coverage of overloads. 
It's up for discussion whether we allow overloading everything or let the users rely on the existing operator overloading mechanisms instead. The one case that we do want to support is the equality operator.

668c079f4e Move AutoGraph to core. This CL moves the entirety of the code base, keeping the frontend autograph module in contrib for backward compatibility. Certain files, like notebooks and the readme file may be referenced from the outside, so a copy of those is kept as well. In addition, the notebooks subdirectory of examples is also kept in contrib because the extension the build file relies on is not available in the PIP package.
