Add -cc1 -ast-dump-xml, an excessively detailed XML dump of the internals
of the ASTs. Only available in assertions builds. No stability guarantee.
This is intended solely as a debugging tool. I'm not sure if the goals
are sufficiently aligned with the XML printer to allow a common
implementation.
Currently just falls back on the StmtDumper to display statements,
which means it doesn't produce valid XML in those cases.
