99a75c56fc * fixed copy-paste error in r15600 
* fixed spilling error after r15600 the same register appears twice in an
    instruction (it was spilled once in that case)

a75016e67b * make sure that registers are of the right type before calling get_alias 
on them (could cause crashes or, in very rare instances, wrong spilling
    code)

e815b923d5 * a_loadfpu_* gets two size parameters: fromsize and tosize 
* fixed downsizing the precision of floating point values
  * floating point constants are now treated using only the minimal
    precision required (e.g. 2.0 is now a single, 1.1 extended etc)
    (Delphi compatible)

51259b697b * more mmx/sse register spilling fixes: 
* operand read/write info for movaps and movapd
    * use "movapd reg,reg" instead of "movaps reg,reg" if appropriate
      so the spilling code can spill the correct size to memory
    * replace movaps/movapd with movss/movsd when spilling to memory
      instead of movq
