The current warning algorithm is too simple. This would be better:
For each function that contains call(s) to setjmp(), compute:
ref_nz The set of variables that might possibly be live
(referenced) after a setjmp() returns a non-zero value.
set_any The set of variables that might possibly be set
(defined) after a call to setjmp() returns.
Issue a warning for all variables in the intersection of the sets.
