Changes for v5:
 * Rebase on david's ppc-for-6.0 branch (fcc83aa7359d)
 * Extract post_load_update_msr (clg)
 * Validate MSR_FOO == HFLAGS_FOO when necessary (david)

Changes for v4:
 * Use hregs_recompute_hflags for hw/ppc/ reset.
   -- Incorporate Cedric's feedback.

Changes for v3:
 * Fixes for linux-user, signal handling and startup.
   -- Oops, the directory in which I did testing for v2
      had a reduced set of targets.

Changes for v2:
 * Do not put tcg internal state into migration, except to
   retain backward compatibility.
 * Do not touch anything in env in ppc_tr_init_disas_context.
 * Do make sure that hflags contains everything that it should.
 * Do verify that hflags is properly updated.
