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. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1632 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
