ffc9e07275 * only don't perform the complex mul->lea optimizations for the Pentium3

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)

a3b877247c * don't perform call/jmp into push/jmp in case we're generating

20206500aa * don't change a sequence of shifts and sub/adds into a lea() in case
