  [SelectionDAG] Pass SDNodeFlags through getNode instead of setFlags. (#149852)

getNode updates flags correctly for CSE. Calling setFlags after getNode
may set the flags where they don't apply.

I've added a Flags argument to getSelectCC and the signature of getNode that takes
an ArrayRef of EVTs.
