Changes since v1:

Patch 1:
  * Use rsb/rsc for gt/le.  Now we always use "rI" as a constraint,
    so we never have to load immediates into registers by hand.

Patch 2:
  * We can't use add_ofs in the while condition and cmp_ofs in the
    reduction and converge; use cmp_ofs always.  Fixes the sparc64
    regression that Peter noticed.
