Rename IFWL classes which do not have CFWL equivalents

This CL moves the IFWL classes that do not have CFWL class buddies to have the
CFWL name. This CL leaves the tree in a weird state of having CFWL be two
hierarchies, one of which is intertwined with the IFWL hierarchy. This should
be commited just before the CL to move the rest of IFWL to CFWL.
