[PATCH] D26310: Add a method to get the list of registered static analyzer checkers.

[Alexander Kornienko via cfe-commits]

alexfh created this revision.

alexfh added a subscriber: cfe-commits.

This provides a better interface for clang-tidy and encapsulates the knowledge
about experimental checkers instead of leaving this to the clients.
