Tests if two statements can be considered equal
Statements can be trivially equal if the kinds match. But they can also be considered equal in the following case A:
ⓘ
discriminant(_0) = 0; // bb1
_0 = move _1; // bb2
In this case the two statements are equal iff
_0
is an enum where the variant index 0 is fieldless, and- bb1 was targeted by a switch where the discriminant of
_1
was switched on
