Automatically clone all symbols in CloneContext()

Almost all transforms should clone all symbols before doing any work,
to avoid any newly created symbols clashing with existing symbols the
source program and causing them to be renamed.

The Renamer is the exception to this, and so an optional flag is used
to prevent automatic cloning of symbols for this transform.
