[avr-chat] Tenfold acceleration of Simulavr is possible.

[Dmitry K.]

Hi all.

I have try to clean body of function `get_program_time'
(src/utils.c) -- by `return 0'.
In result speed of simulation increase:

   Computer #1:   7.54 --> 3.01 sec
   Computer #2:  18.28 --> 1.51 sec

Simulavr is from simulavr-0.1.2.1 tarball.
Run was in autonomous mode, with `-B' option.
