Message:

Add the lexicalEnvironment as an operand to op_create_arguments.

Reviewed by Geoffrey Garen.

This patch only adds the operand to the bytecode. It is not in use yet.

• Adds the lexicalEnvironment register (if present) as an operand to op_create_arguments. Else, adds a constant empty JSValue.
