[clang][docs][dataflow] Added an introduction to dataflow analysis This documentation supports the dataflow analysis framework (see "[RFC] A dataflow analysis framework for Clang AST" on cfe-dev). Since the implementation of the framework has not been committed yet, right now the doc describes dataflow analysis in general. Since this is the first markdown document in clang/docs, I added support for Markdown to clang/docs/conf.py in the same way as it is done in llvm/docs.
