Simon Zünd 9e27dbca79 [debug] Fix crash when live editing unused inner functions
This CL fixes a wrong assumption in the LiveEdit machinery. Namely
the assumption that every FunctionLiteral the parser finds, will have
a corresponding SFI created by the compiler. This assumption does not
hold in all cases. Inner functions that are never referenced by the
outer function don't get an SFI.
