19262ee072 [SystemZ] Use SRST to implement strlen and strnlen
It would also make sense to use it for memchr; I'm working on that now.

ac168b8bc8 [SystemZ] Use CLC and IPM to implement memcmp
For now this is restricted to fixed-length comparisons with a length
in the range [1, 256], as for memcpy() and MVC.

ac6d9bec67 Track IR ordering of SelectionDAG nodes 2/4.
Change SelectionDAG::getXXXNode() interfaces as well as call sites of
these functions to pass in SDLoc instead of DebugLoc.

e72f2027e9 reimplement memcpy/memmove/memset lowering to use MachinePointerInfo
instead of srcvalue/offset pairs.  This corrects SV info for mem 
operations whose size is > 32-bits.

ff7a562751 Implement a bunch more TargetSelectionDAGInfo infrastructure.
Move EmitTargetCodeForMemcpy, EmitTargetCodeForMemset, and
EmitTargetCodeForMemmove out of TargetLowering and into
SelectionDAGInfo to exercise this.

8c0e89925d Create a new TargetSelectionDAGInfo class. This will eventually acquire
SelectionDAG-specific parts of TargetLowering.
