e0cf015159 * refactor function result handling 
* rename methodpointerinit/done to callinitblock/callcleanupblock
  * moved checks in callnode to separate functions
  * funcretnode is now always a simple node instead of a block of
    statements
  * funcret and methodpointer are generated/optimized only in pass_1 so
    a conversion from calln to loadn is much easier
  * function result assignments are much more often optimized to use the
    assignment destination location instead of using a temp

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)

6997121c18 * also perform "SSA" for certain loads (currently derefn, righthand side of 
assignmentn and callparan), reduces number of long lived conflicts.
    Mainly helpful on register-starved cpus such as i386.

eccbc78e04 + support for bitpacked arrays: 
+ use {$bitpacking on/+} to change the meaning of "packed"
      into "bitpacked" for arrays. This is the default for MacPas.
      You can also define individual arrays as "bitpacked", but
      this is not encouraged since this keyword is not known by
      other compilers and therefore makes your code unportable.
    + pack(unpackedarray,index,packedarray) to pack
      length(packedarray) elements starting at
      unpackedarray[index] into packedarray.
    + unpack(packedarray,unpackedarray,index) to unpack
      packedarray into unpackedarray, with the first
      element being stored at unpackedarray[index]
  * todo:
    * "open packed arrays" and rtti for packed arrays are not
      yet supported
    * gdb does not properly support bitpacked arrays

89094457c5 * pass varargs float parameters only in integer registers instead of only
