* bjorn/beam-loader/OTP-9030: (43 commits)
  c: Reduce memory footprint
  erl_posix_msg: Reduce memory footprint
  Introduce a few more variations of the move instructions
  Combine a move + jump sequence into the move_jump instruction
  Optimize and clean-up the exact equality/non-equality instructions
  Optimize addition of a small integer to a variable
  Introduce a special instruction for select_val with two values
  Introduce a few more specialized put_list instructions
  Eliminate the "put_list c n Dst" instructions
  Eliminate the specific move_sd instruction
  Eliminate use of GetArg1() in the badmatch and case_end instructions
  Eliminate use of GetArg2() in the i_element instruction
  Eliminate use of GetArg1() in the fast_element instruction
  Eliminate use of GetArg1() in the jump_on_val* instructions
  Eliminate use of GetArg1() in the select_val instruction
  beam_emu: Eliminate sloppy use of tmp_arg1 and tmp_arg2
  beam_emu: Don't inline helper functions into process_main()
  beam_emu: Clean up calling of the error_handler module
  Simplify a select_val instruction that selects only one value
  Optimize creation of tuples
