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

b57c95043f + support overriding tdef/tsym methods with target-specific functionality: 
o made all (non-abstract) tdef and tsym constructors virtual
   o added c*def/c*sym classref types for every (non-abstract) t*def/t*sym
     class
   o added cpusym unit for every architecture that derives a tcpu*def/tcpu*sym
     class from the base classes, and initialises the c*def/c*sym classes with
     them. This is done so that the llvm target will be able to derive from
     the tcpu*def/sym classes without umpteen ifdefs, and it also means that
     the WPO can devirtualise everything because the c* variables are only
     initialised with one class type
   o replaced all t*def/t*sym constructor calls with c*def/c*sym constructor
     calls
