  [core] WIP fix morph [GH #372]

pass the correct type info to pmc_reuse
allow the 2nd argument to be a Object PMC, so
use Parrot_pmc_reuse_init instead.

TODO:
- non-builtin types via PARROT_CLASS(type)->id
  and Parrot_pmc_reuse_by_class

- morph old values into new type (pmc specific).
  e.g. *Array => Integer needs to assign the elements to the get_integer iv
