184.108.40.206: Fix deportation gc safety bug
* Pin objects that are deported by taking a SAP to a GCd object
* In some cases the object that the SAP is taken to isn't actually
EQ to the one that was deported -> split deportation into
separate alien-type-class-methods for the allocation and the
* Don't do pinning on non-x86oids, since we can't really disable
the GC during all alien calls.
