We are going to deprecate `WITH_RUNTIME` directive. The main reason
behind this change is that `WITH_STDLIB` directive better describes
its meaning, specifically it will add kotlin stdlib to test's classpath.
Some methods (like `size` from kotlin.collections.Collection) have
special rules for mapping and overriding. For example, when we call
`size`, normally there will be `INVOKEVIRTUAL size()` in the bytecode,
but for inline classes it should be `INVOKESTATIC ...$Erased.getSize()`
