Perhaps the easiest mechanism would be via attributes that the FE 
inserts into the variables.  Variable annotations are another way, but 
they don't exist until much later.  Attributes can be added at any point.

OTOH, the middle-end could do interprocedural call-clobbering analysis, 
particularly now that we are getting a stronger IPA infrastructure.
