Fix PR15155: lost vadd/vsplat optimization. During lowering of a BUILD_VECTOR, we look for opportunities to use a vector splat. When the splatted value fits in 5 signed bits, a single splat does the job. When it doesn't fit in 5 bits but does fit in 6, and is an even value, we can splat on half the value and add the result to itself. This last optimization hasn't been working recently because of improved constant folding. To circumvent this, create a pseudo VADD_SPLAT that can be expanded during instruction selection. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175632 91177308-0d34-0410-b5e6-96231b3b80d8

Additional fixes for bug 15155. This handles the cases where the 6-bit splat element is odd, converting to a three-instruction sequence to add or subtract two splats. With this fix, the XFAIL in test/CodeGen/PowerPC/vec_constants.ll is removed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175663 91177308-0d34-0410-b5e6-96231b3b80d8

Fix PR15155: lost vadd/vsplat optimization. During lowering of a BUILD_VECTOR, we look for opportunities to use a vector splat. When the splatted value fits in 5 signed bits, a single splat does the job. When it doesn't fit in 5 bits but does fit in 6, and is an even value, we can splat on half the value and add the result to itself. This last optimization hasn't been working recently because of improved constant folding. To circumvent this, create a pseudo VADD_SPLAT that can be expanded during instruction selection. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175632 91177308-0d34-0410-b5e6-96231b3b80d8
