Add a new interface for describing the behavior of library calls.  This
Currently is sufficient to describe mod/ref behavior but will hopefully
eventually be extended for other purposes.

This isn't used by anything yet.

Yet another nasty spiller bug.
%ecx = op
store %cl<kill>, (addr)
(addr) = op %al

It's not safe to unfold the last operand and eliminate store even though %cl is marked kill. It's a sub-register use which means one of its super-register(s) may be used below.
