8b71994fde Remove unused ShouldFoldAtomicFences flag. 
I think it's almost impossible to fold atomic fences profitably under
LLVM/C++11 semantics. As a result, this is now unused and just
cluttering up the target interface.

abe64dc6f7 Move PPC getSwappedPredicate for reuse 
The getSwappedPredicate function can be used in other places (such as in
improvements to the PPCCTRLoops pass). Instead of trapping it as a static
function in PPCInstrInfo, move it into PPCPredicates with other
predicate-related things.

No functionality change intended.

24a5f30f77 MergeFunc: Make pointer and integer types generate the same hash. 
The logic that actually compares the types considers pointers and integers the
same if they are of the same size. This created a strange mismatch between hash
and reality and made the test case for this fail on some platforms (yay,
test cases).

75299e3a95 Move TryToFoldFastISelLoad to FastISel, where it belongs. In general, I'm 
trying to move as much FastISel logic as possible out of the main path in
SelectionDAGISel - intermixing them just adds confusion.

87c1e42be7 Fix PPC optimizeCompareInstr swapped-sub argument handling 
When matching a compare with a subtract where the arguments of the compare are
swapped w.r.t. the arguments of the subtract, we need to negate the predicates
(or CR bit indices) of the users. This, however, is not the same as inverting
the predicate (negating LT -> GT, but inverting LT -> GE, for example). The ARM
backend seems to do this correctly, but when I adapted the code for the PPC
backend, I introduced an error in this logic.

Comparison optimization is now enabled again by default.
