[Compiler] In ast-numbering add literal to eager_literals before recursing.

Add the function literal to eager_literals before recursing into the literal.
This ensures that the order of eager_literals reflects the order in which
the functions will be called, which in-turn ensures it is compiled first
by the compiler-dispatcher.
