  3. py: Add constant table to bytecode. 

    Contains just argument names at the moment but makes it easy to add
arbitrary constants.

  4. py: Add MICROPY_PORTABLE_CODE, for compiler to produce portable bytec… 

    …ode.

Main changes when MICROPY_PORTABLE_CODE is enabled are:

- qstrs are encoded as 2-byte fixed width in the bytecode
- all pointers are removed from bytecode and put in const_table (this
  includes const objects and raw code pointers)

  5. py: Add MICROPY_PORTABLE_CODE_SAVE, for ability to load/save bytecode. 

    With MICROPY_PORTABLE_CODE, bytecode can be read from a .mpc file and
executed.  With MICROPY_PORTABLE_CODE_SAVE enabled as well, bytecode can
be saved to a .mpc file.
