This isn't testing your binary operators, it is checking direct calls into the
runtime. What you want is "return 1 | 2" (or you might need to do var a = 1;
return a | 2;" to avoid the operation being constant folded. Also this should go
in TEST(PrimitiveExpressions), not CallRuntime (and it would be great to add a
few more in there for SUB, MOD, MUL, DIV, etc.).

Done.
