5ef93e85b8 + added extra "orgsupreg" parameter to do_spill_read/do_spill_written/ 
do_spill_replace routines, will be necessary by llvm register
    allocator to determine the tdef corresponding to that register

    allocator so that it can work both with taicpu and taillvm instructions

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
