Aliaksandr Kalenik edd2f8b37f LibJS: Run reusable steps of FunctionDeclarationInstantiation only once ...

This change moves steps that can be executed only once and then reused
in subsequent function instantiations from
`function_declaration_instantiation` to the ECMAScriptFunctionObject:
- Determine if there are any parameters with duplicate names.
- Determine if there are any parameters with expressions.
- Determine if an arguments object needs to be created.
- Create a list of distinct function names for which bindings need to
  be created.
- Create a list of distinct variable names for which bindings need to
  be created.

This change makes React-Redux-TodoMVC test in Speedometer
run 10% faster :)
