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)

66cf666f65 * optimized storing constants into subsetreg/refs (a packed array of 
boolean can now be as efficient as a set of boolean -- and it is
    on ppc32/64)

658c46b903 * remove tdictionary and tindexarray 
* symtables based on TFPHashObjectList and TFPObjectList
  * rename torddef.typ to torddef.ordtype
  * rename tfloatdef.typ to tfloatdef.floattype
  * rename tdef.deftype to tdef.typ
  * remove obsolete browser code, browcol is kept so the ide
    can still be compiled

2adcae0cd8 * optimized register-register loading of < 64 bit values (removes superfluous code), similar to 3207 for ppc 
* fixed fixref() which did not always treat addresses as 64 bit sizes, resulting in problems using above optimization
* cleanup
