-ast-print and -ast-dump indeed provide different views of the AST.

Like an AST, the CFG is an internal data structure.  Within the compiler, CFGs are generated on-demand from ASTs when they are needed.

Are you asking if it is possible to dump a textual representation of the CFG of a given function from an AST file?  If so, there is currently no driver logic for that, but it is definitely possible.
