     Tell the compiler about alpha, mipseb and mipsel again; fixes #7339

     This reverts the compiler parts of

         Remove registerised code for dead architectures: mips, ia64,
 alpha,
         hppa1, m68k

     In particular, we want to know whether bewareLoadStoreAlignment should
     return True or False for them.

     It also reverts

         Remove missing archs (mipseb, mipsel, alpha) (#5734)

         It doesn't hurt to map these to ArchUnknown since we don't need to
         know anything specific about them, and adding them would be a pain
         (there are a bunch of places where we have to case-match on all
 the
         arches to avoid warnings).
