Simon Pilgrim db134aaec2 [IPO] Disabled 'default only' switch statements to fix MSVC warnings.
@jdoerfert Looks like these are placeholders for incoming abstract attributes patches so I've just commented the code out, even though this is usually frowned upon.

Johannes Doerfert aade782a98 [Attributor] Pass infrastructure and fixpoint framework
NOTE: Note that no attributes are derived yet. This patch will not go in
      alone but only with others that derive attributes. The framework is
      split for review purposes.

This commit introduces the Attributor pass infrastructure and fixpoint
iteration framework. Further patches will introduce abstract attributes
into this framework.

In a nutshell, the Attributor will update instances of abstract
arguments until a fixpoint, or a "timeout", is reached. Communication
between the Attributor and the abstract attributes that are derived is
restricted to the AbstractState and AbstractAttribute interfaces.

Please see the file comment in Attributor.h for detailed information
including design decisions and typical use case. Also consider the class
documentation for Attributor, AbstractState, and AbstractAttribute.
