- Added alignment constraints to memory loads and stores.
- In Cminor and below, removed pointer validity check in semantics of comparisons, so that evaluation of expressions is independent of memory state. - In Cminor and below, removed "alloc" instruction. - Cleaned up commented-away parts. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@945 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
