Add 'umax' similar to 'smax' SCEV. Closes PR2003.
...
Parse reversed smax and umax as smin and umin and express them with negative
or binary-not SCEVs (which are really just subtract under the hood).
Parse 'xor %x, -1' as (-1 - %x).
Remove dead code (ConstantInt::get always returns a ConstantInt).
Don't use getIntegerSCEV(-1, Ty). The first value is an int, then it gets
passed into a uint64_t. Instead, create the -1 directly from
ConstantInt::getAllOnesValue().

Fix an incredibly subtle bug exposed by Ted's change to APInt profiling.
...
AddNodeIDNode does profiling for a ConstantSDNode, but so does
SelectionDAG::getConstant. This profiling should be moved to a common
static function in ConstantSDNode.
