When tests are run in parallel, using the same name for two test outputs might

Simply filter the final state before printing, instead of using pretty_filter.

For now we ignore "unused" label attribute, because the current mecanism

be a label attribute or a function attribute.

Only emits overflow alarms on [a/b] when [a] may be equal to [min_int] AND
[b] may be equal to [-1]. Also reduces the values of [a] and [b] when possible.

According to the C standard, section 6.5.5 §6:
"If the quotient a/b is representable, the expression (a/b)*b + a%b shall equal a;
otherwise, the behavior of both a/b and a%b is undefined."

When an invalid status is emitted for the instance of a precondition at a
callsite, registers as "high priority" the instance as well as the precondition
itself.
