[DAGCombine] Fold redundant select
Recommit bbdf24357932b064f2aa18ea1356b474e0220dde.
Original commit message:
If a chain of two selects share a true/false value and are controlled
by two setcc nodes, that are never both true, we can fold away one of
the selects. So, the following:
(select (setcc X, const0, eq), Y,
(select (setcc X, const1, eq), Z, Y))
Can be combined to:
select (setcc X, const1, eq) Z, Y
