"make check" testcases, for example
2008-02-04-ExtractSubvector.ll and (partially)
CodeGen/Generic/vector.ll.

Added two "FIXMEs" for code that looks dubious to me (but I could be
wrong).

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().

AddNodeIDNode does profiling for a ConstantSDNode, but so does 
SelectionDAG::getConstant.  This profiling should be moved to a common
static function in ConstantSDNode.
