* foreach gets extra argument for passing local data to the
iterator function
* -CR checks also class typecasts at runtime by changing them
into as
* fixed compiler to cycle with the -CR option
* fixed stabs with elf writer, finally the global variables can
be watched
* removed a lot of routines from cga unit and replaced them by
calls to cgobj
* u32bit-s32bit updates for and,or,xor nodes. When one element is
u32bit then the other is typecasted also to u32bit without giving
a rangecheck warning/error.
* fixed pascal calling method with reversing also the high tree in
the parast, detected by tcalcst3 test
name to lowercase(declaration_name). This prevents a normal user from
accessing the routine, but they can still be easily looked up within
the compiler. This is used for helper procedures and should facilitate
the writing of more processor independent code in the code generator
itself (mostly written by Peter)
+ new "createintern" constructor for tcal nodes to create a call to
helper exported using the "compilerproc" directive
+ support for high(dynamic_array) using the the above new things
+ definition of 'HASCOMPILERPROC' symbol (to be able to check in the
compiler and rtl whether the "compilerproc" directive is supported)
* better and generic check if a node can be used for assigning
* export fixes
* procvar equal works now (it never had worked at least from 0.99.8)
* defcoll changed to linkedlist with pparaitem so it can easily be
walked both directions
