Makefile-AVR: add a target for our standard performance test. 

Our standard performance test is to run these three G-code files
in SimulAVR and recording step pulse timings. While this certainly
doesn't cover everything related to possible performance
measurements, it's a good basic standard to compare code changes.

Current performance:
  ATmega sizes               '168   '328(P)   '644(P)     '1280
  Program:  19808 bytes      139%       65%       32%       16%
     Data:   2191 bytes      214%      107%       54%       27%
   EEPROM:     32 bytes        4%        2%        2%        1%

  short-moves.gcode statistics:
  LED on occurences: 888.
  LED on time minimum: 308 clock cycles.
  LED on time maximum: 729 clock cycles.
  LED on time average: 317.393 clock cycles.

  smooth-curves.gcode statistics:
  LED on occurences: 23648.
  LED on time minimum: 308 clock cycles.
  LED on time maximum: 726 clock cycles.
  LED on time average: 354.825 clock cycles.

  triangle-odd.gcode statistics:
  LED on occurences: 1636.
  LED on time minimum: 308 clock cycles.
  LED on time maximum: 719 clock cycles.
  LED on time average: 336.327 clock cycles.
