The `mp_obj_code_t` and `mp_type_code` code object was defined internally in both `py/builtinevex.c` and `py/profile.c`, with completely different implementations (the former very minimal, the latter quite complete). This commit factors these implementations into a new, separate source file, and allows the code object to have four different modes, selected at compile-time: - MICROPY_PY_BUILTINS_CODE_NONE: code object not included in the build. - MICROPY_PY_BUILTINS_CODE_MINIMUM: very simple code object that just holds a reference to the function that it represents. This level is used when MICROPY_PY_BUILTINS_COMPILE is enabled. - MICROPY_PY_BUILTINS_CODE_BASIC: simple code object that holds a reference to the proto-function and its constants. - MICROPY_PY_BUILTINS_CODE_FULL: almost complete implementation of the code object. This level is used when MICROPY_PY_SYS_SETTRACE is enabled. Signed-off-by: Damien George <damien@micropython.org>
