// This test checks that value numbering does not incorrectly propagate the value number for an operand to its
// consuming operator unless the type of the operand and the operator agree.
//
// In particular, in the body of method N, the optimizer will fold the two `ceq` conditions together using a logical
// or of type int32. Value numbering will then determine that one operand to the logical or is a constant `0` (namely,
// the result of `ldloc.0` and attempt to propagate the value number of the logical or's other operand to the logical
// or itself. This should not succeed, as the type of the logical or is int32 and the type of its non-zero operand is
// `ref`.
