7d459cf12a * the compiler now explicitly keeps track of the minimally guaranteed 
alignment for each memory reference (mantis #12137, and
    test/packages/fcl-registry/tregistry1.pp on sparc). This also
    enables better code generation for packed records in many cases.
  o several changes were made to the compiler to minimise the chances
    of accidentally forgetting to set the alignment of memory references
    in the future:
    - reference_reset*() now has an extra alignment parameter
    - location_reset() can now only be used for non LOC_(C)REFERENCE,
      use location_reset_ref() for those (split the tloc enum so the
      compiler can catch errors using range checking)

1536e9e65b + de-uglified the previous hack 
+ made Amiga syscalls to save/restore the frame pointer (do we really need a frame pointer?)
 + some disabled debug comments (to asm source)
 + compiler is now able to generate some VERY basic, but working Amiga-m68k executables

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)
