... behind the v8_enable_external_code_space build flag.
This is a first CL in a row of CLs that will make CodeDataContainer
the only type of objects that could contain references to Code objects
(besides the Code objects embedded into the generated code).
Eventually these changes will allow us to move Code space out of the V8
heap cage.
This CL adds |code| field to ensure that CodeDataContainer keeps the
respective Code object alive and |code_entry_point| field that contains
cached value of the code().InstructionStart().
