Add support for arrow functions

Arrow parameter lists are tricky and require some reparsing
by the standard to avoid conflicts in the parser with
expression statements.

Add an IsArrowFunction flag to the CompiledData::Function. This
information is required in the runtime, when creating Function
objects, as it does influence their behaviour in subtle ways.
