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

[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.

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.

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.

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

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