12484c7699 Add g3 back to the mix and reorder to irritate them anal folk. Actually, it's 
to group appropriately and provide cues to maintainers that the lists don't
need to be ordered.

ffa76df587 Instead of aborting if not a case we can handle specially, break out and 
let the generic code handle it.  This fixes CodeGen/Generic/2005-10-21-longlonggtu.ll on ppc.

also, reindent this code

haven't seen it fire on our testsuite.

6c42f509bc Invert the TargetLowering flag that controls divide by consant expansion. 
Add a new flag to TargetLowering indicating if the target has really cheap
  signed division by powers of two, make ppc use it.  This will probably go
  away in the future.
Implement some more ISD::SDIV folds in the dag combiner
Remove now dead code in the x86 backend.

763a62efa6 Add some pattern fragments to simplify the repetitive parts of the patterns 
for some common ops and use them for a few examples.  Andrew, if you like
this, feel free to convert the rest over, if you hate it, feel free to
revert.

dc1a2a1f19 Move the target constant divide optimization up into the dag combiner, so 
that the nodes can be folded with other nodes, and we can not duplicate
code in every backend.  Alpha will probably want this too.
