`ASTPrinter` allows setting the ouput to any O-Stream, but that printer creates
source-code-like syntax (and is also marked with a `FIXME`). The nice,
colourful, mostly human-readable `ASTDumper` only works on the standard error,
which is not feasible in case a user wants to see the AST of a file through a
code navigation/comprehension tool.
This small addition of an overload solves generating a nice colourful AST block
for the users of a tool I'm working on, CodeCompass
<http://github.com/Ericsson/CodeCompass>, as opposed to having to duplicate the
behaviour of definitions that only exist in the anonymous namespace of
implementation TUs related to this module.
