This extends the select lowering to support floating-point selects. The lowering depends on SSE instructions and that the conditon comes from a floating-point compare. Under this conditions it is possible to emit an optimized instruction sequence that doesn't require any branches to simulate the select. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211544 91177308-0d34-0410-b5e6-96231b3b80d8
