Add SDNodes for umin, umax, smin and smax.
This adds new SDNodes for signed/unsigned min/max. These nodes are built from
select/icmp pairs matched at SDAGBuilder stage.
This patch adds the nodes, as well as legalization support and sets them to
be "expand" for all targets.
NFC for now; this will be tested when I switch AArch64 to using these new
nodes.
