Replace the saved_lexical_environments stack in ExecutionContextRareData with explicit register-based environment tracking. Environments are now stored in registers and restored via SetLexicalEnvironment, making the environment flow visible in bytecode. Key changes: - Add GetLexicalEnvironment and SetLexicalEnvironment opcodes - CreateLexicalEnvironment takes explicit parent and dst operands - EnterObjectEnvironment stores new environment in a dst register - NewClass takes an explicit class_environment operand - Remove LeaveLexicalEnvironment opcode (instead: SetLexicalEnvironment) - Remove saved_lexical_environments from ExecutionContextRareData - Use a reserved register for the saved lexical environment to avoid dominance issues with lazily-emitted GetLexicalEnvironment
