03fa8336de o several avr fixes 
* handle function result of FPC_MUL_WORD correctly
  * use mov ...,r1 to load a register with zero instead of clr ..., this might enable the register allocator to 
    coalesce these moves in the feature
  * use tst/dec instead of cpi/sub in the shifting loops, this reduces register pressure on r16 and higher
