Currently initializers (in, say, a Constructor) is included in the
outline if it is not null. Null values are explicitly added only when
building the bodies.
This has the unfortunate effect of initializers copied in the outline
phase (e.g. for mixins) not including the null initializer. If, however,
later recompiling (even without changes, and if the split is correct)
suddenly an initializer changes.
This CL fixes the issue by initializing to null in the outline phase.
