Fix for PR2687: Add patterns to match sint_to_fp and fp_to_sint for <2 x
i32>. This is a little messy, but it works. We should really get rid of the intrinsics, though, since they map perfectly well to standard LLVM instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55864 91177308-0d34-0410-b5e6-96231b3b80d8
