[committed] sim/avr: clear memory before loading a program

[Tristan Gingold]

Hi,

because the memory for the sram and the flash is static in interp.c,  
we should clear it before loading
a program to erase effect of a previous run when the simulator is part  
of gdb.

Approved privately by Joel.

Tristan.
