when has_simple_parameters_ is false in DeclareArguments
- According to https://tc39.es/ecma262/multipage/ordinary-and-exotic-objects-behaviours.html#sec-functiondeclarationinstantiation
step 28, arguments var declaration in function should be binding to
arguments parameterBindings when has_simple_parameters_ is false.
- According to https://tc39.es/ecma262/multipage/ordinary-and-exotic-objects-behaviours.html#sec-funct>
step 18, we should set arguments_ is nullptr if "arguments" is an element of lexicalNames
only when has_simple_parameters is true.
