Dynamically allocate arguments to java entry point
...
This was already done for arguments that had more than one
object type.
The motivation for this is that when nondet-initialising the
argument with automatic local allocation we were creating the
object to be pointed to and only initialising it when the
argument is non-null, and then symex couldn't resolve the
class identifier, which stopped it from doing various
optimisations and producing a simpler formula.

Value sets: Support bit operations over pointers
...
Bit operations on pointers are used to defend against side channels
resulting from speculative execution. Hence we need to support these.
Without the support in value sets we silently just returned "unknown"
and thus subsequent dereferencing would fail.

Support OBJECT_SIZE over string constants
...
Pointer checks (including __CPROVER_{r,w}_ok) over string constants
should succeed when the access is within bounds. To do so, we must no
return non-deterministic values for the object size of string constants.

SMT-LIB 3 will bring function applications for terms that aren't symbols

A non-constant offset is stored as "unknown," which does include an
offset of zero. As constant + zero == constant we should not conclude
that the constant is not contained in the set.
