3e98429418 Revert " * patch by J. Gareth Moreton: Nothing (NOP) node optimisation, resolves #38194" 
This reverts commit c2ff85ac5b.

That change duplicates the logic of tstatementnode.simplify in
tblocknode.simpify in a very complex way, and in case of issue #39336 results
in adding a non-tstatementnode in a tblocknode, which is illegal. If
tstatementnode.simplify cannot catch all cases, then that one should
preferably be improved instead (and if not possible, we can look into
catching those edge cases in tblocknode.simplify rather than duplicating
everything).

Resolves issue #39336

f26735fc77 * execute the tempinitcode whent the tempcreate node gets processed rather 
than when the first temprefnode to it gets processed. Solves the issue
    the foreachnodestatic processes the tempinitcode when seeing the
    tempcreatenode and ignores it when seeing temprefnodes, even though
    it may actually be executed/generated for the temprefnode. It's
    impossible to easily process it for the "correct" temprefnode
    (since there may be multiple temprefnodes for the same tempcreatenode)
   o fixes tarray12 for Darwin/i386 and Linux/i386

ac1e0f96bd * replaced tentryfile.get/putsmall/normalset() with a common tget/putset 
that expects an open array of byte, and use it for all sets
   o since all sets need to be typecasted to an array type of the appropriate
     size, we'll get a compilation error in case this needs to be done and
     that also tells us at the same time that the ppu version will need to
     be increased
  * enabled {$packset 1} for the compiler, as this is now safe with the above
    changes

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.

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

179c1ab328 * changed ttemp*node.tempinfo^.flags to a private field, and added setters 
and getters for the ttemp*node classes instead
   o this will allow descendants to prevent certain flags from being added
     or removed. E.g. for LLVM, certain temps must never be put in registers
     because it cannot typecast a value in a register from a non-record/array
     type to an array type without forcing it to memory (so if that is done
     on an lvalue, the result will be written to the memory temp instead of
     to the register)
