Fix pr11194. When promoting and splitting integers we need to use
ZExtPromotedInteger and SExtPromotedInteger based on the operation we legalize. SetCC return type needs to be legalized via PromoteTargetBoolean. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142660 91177308-0d34-0410-b5e6-96231b3b80d8
