  1. Codegen ZSTs without an allocation 

    This makes sure that &[] is just as efficient as indirecting through
unsafe code (from_raw_parts). No new stable guarantee is intended about
whether or not we do this, this is just an optimization.

  2. Fix broken test 

    Testing for ASLR by casting &ZST to *const _ is not useful, there's no
guarantee that &ZST produces an ASLR'd pointer.
