7a0ae38700 + also specify the parameter def when allocating a parameter via
getintparaloc + adapted all call sites of getintparaloc. This
    led to a number of additional, related changes:
   o corrected the type information for some getintparaloc parameters
   o don't allocate some intparalocs in cases they aren't used
   o changed "const tvardata" parameter into "constref tvardata" for
     fpc_variant_copy_overwrite to make pass-by-reference semantics
     explicit
   o moved a number of routines that now have to call find_system_type()
     from cgobj to hlcgobj so that cgobj doesn't have to start depending
     on the symtable unit
   o added versions of the cpureg alloc/dealloc methods to hlcgobj that
     call through to their cgobj counter parts, so we can call save/restore
     the cpu registers before/after calling system helpers from hlcgobj
     (not implemented in hlcgobj itself, because all basic register
      allocator functionality is still part of cgobj/cgcpu)

283018a3bf * changed tprocdef.funcretloc[] from a tlocation into a tcgpara so it can
represent complex locations (required for full x86-64 ABI support,
    which is not yet implemented) -> lots of special result handling
    code has been removed and replaced by the parameter handling
    routines
  + added support for composite parameters (and hence function
    results) to tcg.a_load_ref_cgpara() (so it can be used for
    handling, e.g., 64 bit parameters on 32 bit platforms)
  * the above fixed writing past the end of allocated memory when
    handling records returned in registers on x86-64 whose size is
    not a multiple of 8 bytes (mantis #16357)
  - removed the x86-64 and PPC specific versions of a_load_ref_cgpara(),
    as they are now handled correctly by the generic version
  * moved the responsibility of allocating tcgpara cpu registers
    (using paramanager.allocparaloc()) from the callers of
    cg.a_load*_cgpara() to the cg.a_load*_cgpara() methods
    themselves (so the register allocation can be done efficiently
    when dealing with function results)
  * for the above, renamed paramanager.alloc/freeparaloc() to
    paramanager.alloc/freecgpara(), and use paramanager.allocparaloc()
    to allocate individual pcgparalocations instead
  * fixed the register size of SSE2 function result registers for
    x86-64 (when used for floating point), which results in removing
    a few superfluous "movs? %xmm0,%xmm0" instructions
  * fixed compilation of paramanagers of avr, m68k and mips after r13695
    and also updated them for these new changes

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)
