09207563d5 + hlcg implementation of gen_load_para_value(); no support yet for copying
value parameters when necessary, nor for -gt variable trashing

9a9ea1f257 + limited thlcg.gen_load_cgpara_loc() implementation (only loc_reference
support), passed through to original ncgutils version in thlcg2ll
  + thlcgobj.location_force_mem() implementation
  * order parameters for jvm similar to those for i386 without fixed_stack,
    so we don't need temporary paralocations
  * converted most of ncgcal to thlcg
  * disabled special handling for virtual methods for jvm in ncgcal, as all
    invocations are name-based there
  + njvmcal with special jvm callnode support:
   o always move the function result into a memory temp
   o when freeing an unused function result, use a_pop(2) and adjust
     the internal evaluation stack height counter
   o after the call instruction, adjust the evaluation stack height counter
     by subtracting the number of the pushed parameter slots, adjusted for
     the slots taken up by the function result

71deda6f50 + added interface to ncgutil.gen_load_loc_cgpara() to hlcgobj + generic
implementation (without loc_©mmregister support)
  * moved ncgutil.gen_load_return_value() to hlcgobj, and factored out
    architecture-specific behaviour to load an uninitialised function result
    into a virtual method (+ JVM-specific implementation of that method),
    gen_load_uninitialized_function_result()
  + added hlcgx86 unit and thlcgx86 type to override the
    thlcgobj.gen_load_uninitialized_function_result() method for x87
    function results; the i386 and x86_64 units now instantiate thlcgx86
    instead of thlcg2ll
  * moved calling of ncgutil.gen_load_loc_cgpara() from ncgcal also to hlcgobj
  -> returning function results works for JVM

07130a0c71 + added register allocation methods from cgobj also to hlcgobj,
call through to cgobj

db203431b2 + hlcgobj: high level code generator class. It has basically the same
interface as cgobj, except that all type parameters are defs instead
    of tcgsize. Also includes some procedures from ncgutil (over time,
    all of ncgutil will probably integrated here so it can be easily
    overridden)
  + hlcg2ll: pass-through implementation of thlcg that forwards everything
    either to cgobj or ncgutil, for use by the classic code generator
    clients (all current platforms)
  + added "def" field to tcgpara to record the tdef of the parameter
    (used by the high level code generator)
