  4. resolve instances to ty::Instance directly 

    This removes the duplication between collector, callee, and (eventually)
MIRI.

  5. refactor away callee::Callee and translate virtual calls through a MI… 

    …R shim

These changes are in the same commit to avoid needing to adapt
meth::trans_object_shim to the new scheme.

One codegen-units test is broken because we instantiate the shims even
when they are not needed. This will be fixed in the next PR.

  6. collector: collect functions when they are called/reified 

    This avoids the creation of unneeded vtable shims.

  10. translate drop glue using MIR 

    Drop of arrays is now translated in trans::block in an ugly way that I
should clean up in a later PR, and does not handle panics in the middle
of an array drop, but this commit & PR are growing too big.
