aca9727418 + OptimizeForLoop: convert for-loops into zero-based backward for-loops if possible, for most architectures, this results in simpler code

254b85c352 + new pio_inline_forbidden flag to indicate that while parsing the
implementation the compiler determined the routine must never be
    inlined
   o difference with po_noinline: can also be set in the implementation
   o difference with pio_inline_not_possible: it indicates that e.g.
     LLVM must not inline the routine either

b625afe800 * never inline routines that call get_frame (otherwise get_frame would return
the frame of the caller rather than of the current routine, which could
    cause e.g. stackframes to be missed in RTL helpers that are known to be
    only called from run time error routines)

4d6b8a6c45 fixed the messy state of messages after recent custom attributes merge. fixed a typo, fixed double definition of message 3350, restored a message that was removed but still used, so the build passes at least.

b2932393df Reintegration of Custom Attributes branch by Joost van der Sluis with patches reworked by Svetozar Belic [patch 1/3]
Implemented attributes for class types and properties (based on work by Joost van der Sluis). Added TCustomAttribute - a base class for attributes. Added TUnitInfo record to RTTI. It contains the unit name and unit options (for now only a flag which specifies if the unit contains attributes). Added several tests for attributes.

e56b58c2b0 * factored out checks whether a procdef's symbol needs to be global, and
the generation of the procdef's asmsymbols
   o also removed unnecessary definition of procdef alias symbols for Darwin
     (they are already defined in ncgutil.alloc_proc_symbol)

3fee990218 * on Mach-O, PECOFF and ELF platforms, write local symbols as hidden/
private_extern (or plain global in case of PECOFF, as the effect is
    the same there): visible across object files, but they become local
    when linked into a binary/library. This enables cross-unit inlining
    of functions accessig implementation-only symbols.

243c967967 Commit of new debug feature implemented by J. Gareth Moreton
Allows compilation of compiler using -dDEBUG_NODE_XML
  which will generate a NAME-node-dump.xml file for each 
  unit, program or library compiled,
  containing a XML description of the nodes handled during
  compilation of the unit, program or library.

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.

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 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()

2f8fcf7819 + new tf_use_psabieh target flag to indicate a target uses PSABI/Dwarf EH
o use this flag to set the personality routine of a function if it uses
     exception handlinga
   o also define FPC_USE_PSABIEH if this target flag is set
   o set this target flag for darwin/x86-64 if the compiler is compiled with
     -dllvm

4cd6f59bc3 * changed create_hlcodegen into a procvar, so that we don't have to insert
hlcgllvm in the uses clause of every unit that calls create_hlcodegen
   o prevents dependency cycles that can cause llvm codegen units to init
     before the cpu variants, which is bad since the llvm versions have to
     override the cpu variants in their init code (+ added checks in the
     init code that they are in fact initialised later)

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)

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
