Johnni Winther 7fce125300 [cfe,kernel] Add AstPrinter 
This CL adds a Node.toText method together with an AstPrinter. These
facility and better toString implementation on AST nodes while allowing
for toString independent printing of AST to use in testing. This also
add support for an integrated toString of custom/internal nodes.

Some work is still needed in bringing the toString implementation on
all nodes to the old quality, and not all internal nodes have
customized textual representations yet. This work is left for future
CLs.
