Merge of branch "unsigned-offsets":
- In pointer values "Vptr b ofs", interpret "ofs" as an unsigned int.
(Fixes issue with wrong comparison of pointers across 0x8000_0000)
- Revised Stacking pass to not use negative SP offsets.
- Add pointer validity checks to Cminor ... Mach
to support the use of memory injections in Stacking.
- Cleaned up Stacklayout modules.
- IA32: improved code generation for Mgetparam.
- ARM: improved code generation for op-immediate instructions.
