This will be the way to create types with destructors.

Emit dead goto-instructions on MIR StatementDead (rust-lang#3063)
0cc4b24 
This commit adds a new `Dead` goto-instruction that gets codegened
whenever Kani sees a MIR `StatementDead` statement. This new
goto instruction corresponds to the CBMC [code_deadt](
https://diffblue.github.io/cbmc/classcode__deadt.html) statement
that marks the point where a local variable goes out of scope.

This new instruction is needed to detect invalid accesses of dead local
variables.

The commit also codegens a CBMC `Decl` instruction upon seeing a MIR
StatementLive. This ensures that variables that go out of scope at the
end of a loop are not falsely marked as having a dead dereference when
they are accessed on the next loop iteration.

Resolves rust-lang#3061.

This is a follow-up on rust-lang#3063 that adds a test with multiple crates to
make sure this scenario is correctly handled and that Kani reports the
bug.
