…dd-module rules (#912) Co-authored-by: automergerpr-permission-manager[bot] <190534181+automergerpr-permission-manager[bot]@users.noreply.github.com>
This PR adds the [volatile_store](https://doc.rust-lang.org/std/intrinsics/fn.volatile_store.html) intrinsic. For this semantics, memory being "volatile" is meaningless as the we are not compiling any further, and aren't modeling any compiler optimisations that could occur if we were to. Therefore this is implemented as a simple dereference of the pointer and store of the value provided at that location.
The staged function evaluation created issues with the SMT solver (unevaluated terms could contain `#lookupDiscriminant` calls while the path condition held `#lookupDiscrAux` constraints). Making the first evaluation step a rewrite changes the step counters but avoids this problem altogether because rewrite symbols don't normally go to the SMT solver.
