68b5ca633c ppc platforms: fix missing TOC restoration room 
PPC platforms that use a TOC can never use a tail call to call a different
routine that potentially accesses globals, as it may use a different TOC and
then the linker must be able to insert an instruction after the branch to
restore the original TOC register value on "return". Even if FPC code itself
does not use the TOC register, it's still required since
  1) the linker does not know this, and
  2) the FPC code might still be called from other code that does use it

a4672fbd1c o based on a patch by Rika, resolves #39401: 
* use Base64 (62=_, 63=$) encoded FNV hash (instead of CR-32) to shorted identifiers
    * renamed fpccrc to fpchash

cc315e0ac7 * fix tw3930 after r37927 
o "unique" class (and interface) type aliases should actually not exist at
     all except for overload resolution. All the rest (VMT, UUID, RTTI, ...)
     should be taken from the aliased class/interface
   o there is one Delphi-incompatibily left after this change, but it shouldn't
     matter: tw8180 does not compile if you change the declaration to
     "tcl=class(TInterfacedObject,XStr,iinterface)", while Kylix does compile
     that. It doesn't really matter though, because in Kylix this actually
     adds iinterface twice as implemented interface, so there is no point
     in accepting this.

a73b723c1d * when using a dummy file position for an interface wrapper, set 
the module to the current module. This is required in case of -al,
    because when writing source lines to the assembly output the input
    file position gets changed. Since the wrappers are generated at the
    end of a unit's compilation, that's no problem if that input file
    belongs to the current unit. It was hardcoded to the unit with id 1
    before though, which is the main unit specified on the command line
    and that one could be different (fixes compilation of win32 buildrtl
    with -al after r37961)

d35377fdee * workaround for debug info for interface method wrappers: give them the 
line number information of the method declaration if it's in the current
    unit, and otherwise the first line of the current unit (mantis #14399)

b813fc641f * put data that's used by the VMT into the same section (that also means changing some sections from rodata_norel to rodata); this way the amount of sections per class is reduced (e.g. two for classes that inherited from a class with interfaces)

7d15b688e8 * TInterfaceEntry changed to a variant record, that overlays a CodePointer on 
top of the IOffset: SizeUInt field, because it is sometimes used as a
  CodePointer (for etStaticMethodResult and etStaticMethodClass) and sometimes
  as a SizeInt and these two types can be of different size in certain i8086
  memory models

   o removed all places where AB_INDIRECT symbols were explicitly generated
   o only generate AB_INDIRECT symbols for AT_DATA on systems_indirect_var_imports

     dereferenced by code in RTL units) -> use new AT_DATA_FORCEINDIRECT type
