7ea0429d40 + added new compiler debug ifdef DEBUG_INSTRUCTIONREGISTERDEPENDENCIES, which 
adds instruction register usage info to the assembly output (only register
  reads for now, but register writes will also be added later). Useful for
  debugging InstructionLoadsFromReg and other similar functions.

cd3f064a33 + enabled postpeepholeopts phase 
+ optimize "integer op" followed by comparison of target register with zero
    to a variant of that integer op which sets the flags (ppc)
  + change rlwinm. instructions which do nothing but an "and" operation into
    andi./andis., since the rlwinm. is cracked on the G5 while andi./andis.
    isn't

ec959955bd * fixed generic jumps optimizer and enabled it for ppc (the label table 
was not being initialised -> getfinaldestination always failed, which
    caused wrong optimizations in some cases)
  * changed the inverse_cond into a function, because tasmcond is a record
    on ppc
  + added a compare_conditions() function for the same reason
