Update crucible, semmc submodules; adapt to GaloisInc/crucible#906

This updates the `crucible` submodule to include GaloisInc/crucible#906
(`Control granularity of reading uninitialized memory`), as well as the
`semmc` submodule to bring in corresponding changes on its side
(GaloisInc/semmc#69). Some additional `?memOpts :: MemOptions` constraints
needed to be added to some functions in `macaw-symbolic` and
`macaw-refinement` as a result.
