FIX #1038: failure of selector-thunk machinery to do its job
After a couple of abortive attempts, I think I've got this right.
When the GC sees a chain of the form

   snd (_, snd (_, snd (_, ...)))

it can now deal with an arbitrary nesting depth, whereas previously it
had a depth limit which was necessitated by the use of recursion.  Now
we chain all the selector thunks together in the heap, and go back and
update them all when we find the value at the end of the chain.

While I was here I removed some old cruft in eval_thunk_selector()
which was carefully manintaing invariants that aren't necessary any
more, the main one being that evacuate() can safely be passed a
to-space pointer now.

In addition to validate I've tested building a stage3 compiler with
and without +RTS -c, so I'm reasonably sure this is safe.

Fix bug #1725 (Haddock links between packages)
Resolving this bug is a bit tricky, it boils down to the question: Should the
Haddock links between packages include the package version or not?

Pro: We can differentiate between various versions of the same package,
installed all at once. (How often does this really happen in practice?)

Cons: When package A refers to a package B, and B is later upgraded, links
in A's documentation will break. Furthermore, if an *additional* version of
B is installed, which version should A refer to?

Because IMHO it is not clear what to do when version numbers are included,
let's leave them out. If somebody has a better idea, feel free to submit a

Tune coalescing in non-iterative register allocator

conservative coalescing for subseqent passes.

Aggressive coalescing is a cheap way to eliminate lots of the reg-reg
moves, but it can make the graph less colorable - if we turn it on
for every pass then allocation for code with a large amount of register
pressure (ie SHA1) doesn't converge in a sensible number of cycles.
