Previously, for a property named `x` in the companion object of a class
named `Foo`, we generated:
- `Foo.access$getX$cp`, consisting of `GETFIELD Foo.x` and lateinit
assertion
- `Foo.Companion.getX`, consisting of `INVOKEVIRTUAL Foo.access$getX$cp`
Now, we generate:
- `Foo.access$getX$cp`, consisting of `GETFIELD Foo.x`
- `Foo.Companion.getX`, consisting of `INVOKEVIRTUAL Foo.access$getX$cp`
and lateinit assertion
The reason is that this way we can avoid generating another accessor and
reuse `Foo.access$getX$cp` in case `isInitialized` is called on a
lateinit property from companion.
For private properties, getX is not generated, but instead the assertion
is generated on each access to the field (which can be improved, see
KT-28331). The same happens for access to non-private properties from
inside the same context where they're declared.
