py: Remove 5 TODOs in emitbc, objrange and repl.

These TODOs don't need to be done:

- Calling functions with keyword arguments is less common than without
  them, so adding an extra byte overhead to all calls regardless of whether
  they use keywords or not would overall increase generated bytecode size.

- Restricting `range` objects to machine-sized ints has been adequate for
  a long time now, so no need to change that and make it more complicated
  and slower.

- Printing spaces in tab completion does not need to be optimised.
