with a vector condition); such selects become VSELECT codegen nodes. This patch also removes VSETCC codegen nodes, unifying them with SETCC nodes (codegen was actually often using SETCC for vector SETCC already). This ensures that various DAG combiner optimizations kick in for vector comparisons. Passes dragonegg bootstrap with no testsuite regressions (nightly testsuite as well as "make check-all"). Patch mostly by Nadav Rotem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139159 91177308-0d34-0410-b5e6-96231b3b80d8
