6423c6c0e8 Don't do pre-splitting if doing so would create a value join that did not 
exist before.  Updating the live intervals in that care is tricky in the general
case.

Evan, if you see a tighter guard condition for this, let me know.

579a024661 Add a new MergeFunctions pass. It finds identical functions and merges them. 
This triggers only 60 times in llvm-test (look at .llvm.bc, not .linked.rbc)
and so it probably wont be turned on by default. Also, may of those are likely
to go away when PR2973 is fixed.

3d0f5afefb Fix PR2986: do not use a potentially illegal 
type for the shift amount type.  Add a check
that shifts and rotates use the type returned
by getShiftAmountTy for the amount.  This
exposed some problems in CellSPU and PPC,
which have already been fixed.
