e5c2d13671 * Do not set pi_needs_got in current_procinfo.flags at the node level, since the GOT usage can only be estimated there. Instead set the pi_needs_got flag at places where the GOT register is accessed during the code generation. This eliminates generation of the unneeded initialization of the GOT register and fixes linker errors when the _GLOBAL_OFFSET_TABLE_ symbol is referenced but no actual GOT references are present.

bc77aad3d9 * give an error when trying to call through to a C varargs routine with a 
high level code generator
   o we cannot create a high-level stub in that case

503ea604f3 + nolinline modifier to specify that a routine must never be inlined

51e68eb302 * fixed several places where the interface crc could change: 
o unsetting po_inline while parsing the implementation for various reasons
     (interprocedural goto/label, accessing a local in a parent frame,
      having nested procedures)
   o instead handle this via the pio_inline_not_possible flag
   o noreturn can no longer be specified only in the implementation

91d5457b38 * moved around/replaced the following procedures to stop nflw from depending 
on pdecsub (node units should not depend on parser units):
   o maybe_add_public_default_java_constructor()
   o handle_calling_convention()
   o create_finalizer_procdef() (replaced with create_outline_procdef())
   o insert_record_hidden_paras()
   o handle_calling_convention()
   o proc_add_definition()
   o build_parentfpstruct()
   o maybe_guarantee_record_typesym()
   o get_first_proc_str()
  * factored out the creation of a procinfo for a nested procdef based on a
    subnodetree of the current procdef into tprocinfo.create_for_outlining()

3a5a69619e * moved initialisation of parentfpstruct to just behind where the local vars 
get initialised, so that parameters in this struct are already available
    in any wrappers generated for the parent routine (e.g. in case self is
    moved to the parentfpstruct in a destructor, which calls beforestruction
    in its wrapper)

b96a8aee61 * don't generate tempsfinalize nodes in except filter procdefs, as that would

3b9f5a5e96 * moved finalization of code generator temps to a node, so it can be getcopy'd 
(needed for LLVM, where we need two copies of the finally code: one in case
     an exception occurs, and one in case none is raised)
   o also first finalize parameters and only then code generator temps, since
     in theory the former could create more of the latter

48b149acd4 New tokens for new management operators: Initialize, Finalize, AddRef and Copy. Small code adjustment for parser (pdecobj.pas, pstatmnt.pas, psub.pas, ptype.pas) was required because few of old token has from now value which is outside range of set: _CONSTRUCTOR, _FINALIZATION. 
New tokens for operators:
  * _OP_INITIALIZE, _OP_FINALIZE, _OP_ADDREF, _OP_COPY

New tokens:
  * _INITIALIZE, _FINALIZE, _ADDREF, _COPY
