Remove the optimisation of avoiding scavenging for certain objects
Some objects don't need to be scavenged, in particular if they have no
pointers. This seems like an obvious optimisation, but in fact it
only accounts for about 1% of objects (in GHC, for example), and the
extra complication means it probably isn't worth doing.

GC refactoring: change evac_gen to evac_step

GC refactoring: make evacuate() take an StgClosure**
Change the type of evacuate() from
StgClosure *evacuate(StgClosure *);
to
void evacuate(StgClosure **);
So evacuate() itself writes the source pointer, rather than the
caller. This is slightly cleaner, and avoids a few memory writes:
sometimes evacuate() doesn't move the object, and in these cases the
source pointer doesn't need to be written. It doesn't have a
measurable impact on performance, though.

Initial parallel GC support
eg. use +RTS -g2 -RTS for 2 threads. Only major GCs are parallelised,

Refactoring of the GC in preparation for parallel GC
This patch localises the state of the GC into a gc_thread structure,
and reorganises the inner loop of the GC to scavenge one block at a
time from global work lists in each "step". The gc_thread structure
has a "workspace" for each step, in which it collects evacuated
objects until it has a full block to push out to the step's global
list. Details of the algorithm will be on the wiki in due course.
At the moment, THREADED_RTS does not compile, but the single-threaded
GC works (and is 10-20% slower than before).

Fix nasty Simplifier scoping bug
This bug was somehow tickled by the new code for desugaring
polymorphic bindings, but the bug has been there a long time. The
bindings floated out in simplLazyBind, generated by abstractFloats,
were getting processed by postInlineUnconditionally. But that was
wrong because part of their scope has already been processed.
That led to a bit of refactoring in the simplifier. See comments
with Simplify.addPolyBind.
In principle this might happen in 6.8.3, but in practice it doesn't seem
to, so probably not worth merging.
