move single basic blocks that are neither fallen into nor fall out of into

a place more useful. In particular, if we can put them in a place where code
will be able to fall into it, do so. Otherwise, put it in a place it can fall
through into a successor. Otherwise, if preventing a fallthrough, move to the
end of the function, out of the way.

3 Changes:
...
1. Better document what is going on here.
2. Only hack on one branch per iteration, making the results less conservative.
3. Handle the problematic case by marking edges executable instead of by
playing with value lattice states. This is far less pessimistic, and fixes
SCCP/ipsccp-gvar.ll.

This provides stuff like:

lwz r18, 68(r1)

Three changes:

1. Remove a bunch of ifdef'd code.
2. When a block just contains an uncond branch, change all blocks branching
to it to jump to the destination instead.
3. If branch analysis tells us some edges in the machinecfg are not actually
possible, remove them.
#2 triggers a suprisingly large number of times.

Corrected load folding check. We need to start from the root of the sub-dag
...
being matched and ensure there isn't a non-direct path to the load (i.e. a
path that goes out of the sub-dag.)

When SimplifySetCC was moved to the DAGCombiner, it was never removed from
...
SelectionDAG and it has since bitrotted. Remove the copy from SelectionDAG.
Next, remove the constant folding piece of DAGCombiner::SimplifySetCC into
a new FoldSetCC method which can be used by getNode() and SimplifySetCC.
This fixes obscure bugs.
