Add a ":dump_decl <name>" command to the REPL, for debugging purposes.

This particular command is useful for exploring the ASTs generated by
the Clang importer. For example

  import Cocoa
  :dump_decl NSArray

shows all of the imported methods in both NSArray (which only has two
methods) and its categories (which have many, many methods).
