Summary:
Add support for overloaded matchers.
This composes with other features, like supporting polymorphic matchers.

Summary:
Add printToStream*(llvm::raw_ostream&) methods to Diagnostics, and reimplement everything based on streams instead of concatenating strings.
Also, fix some functions to start with lowercase to match the style guide.

Summary:
Change how error messages are constructed and stored in Diagnostics.
Separate the notion of 'context' when recursing down in the parser and actual errors.
This will simplify adding some new features, like argument overloading and error recovery.

Add support for polymorphic matchers. Use runtime type checking to determine the right polymorphic overload to use.

- Added conversion routines and checks in Matcher<T> that take a DynTypedMatcher.
- Added type information on the error messages for the marshallers.
- Allows future work on Polymorphic/overloaded matchers. We should be
  able to disambiguate at runtime and choose the appropriate overload.

Summary:
 Parser/Registry argument enhancements.
  - 2 argument support.
  - unsigned values support.

This library supports all the features of the compile-time based ASTMatcher
library, but allows the user to specify and construct the matchers at runtime.
It contains the following modules:
 - A variant type, to be used by the matcher factory.
 - A registry, where the matchers are indexed by name and have a factory method
   with a generic signature.
 - A simple matcher expression parser, that can be used to convert a matcher
   expression string into actual matchers that can be used with the AST at
   runtime.

Many features where omitted from this first revision to simplify this code
review. The main ideas are still represented in this change and it already has
support working use cases.
Things that are missing:
 - Support for polymorphic matchers. These requires supporting code in the
   registry, the marshallers and the variant type.
 - Support for numbers, char and bool arguments to the matchers. This requires
   supporting code in the parser and the variant type.
 - A command line program putting everything together and providing an already
   functional tool.
