DCE: clean up the cfg for all functions that were processed. (#4840)

Which functions are processed is determined by which ones are on the
call tree from the entry points before dead code is removed.  So it is
possible that a function is process because it is called from an entry
point, but the CFG is not cleaned up because the call to the function
was removed.

The fix is to process and cleanup every function in the module.  Since
all of the dead functions would have already been removed in an earlier
step of DCE, it should not make a different in compile time.

Fixes #4731
