Third fix. SharedFunctionInfo of lazy compiled functions is not fully pupulated
(since we haven't yet parsed) so here, after parse, we need to remember more
data on the shared info and CompilationInfo.

The preparser should be able to detect this and store it in the preparser data
with the other data that are set for lazy functions.
On the other hand, if this is sufficient, I guess it'll do.

Preparser doesn't yet detect strict mode. Once it does (and it will have to for
early errors) I'll remove this.
