Merge git://github.com/darchon/clash into cλash

Disabled foldr generation again, it should either be updated to the
shorter form from my last commits, but preferably foldl should be
abstracted to handle both.

* git://github.com/darchon/clash:
  Added builtin function foldr
  Foldl correctly handles empty vectors

Conflicts:
	Generate.hs
	GlobalNameTable.hs
