[X86][SSE] Improve recognition of uitofp conversions that can be performed as sitofp With D24253 we can now use SelectionDAG::SignBitIsZero with vector operations. This patch uses SelectionDAG::SignBitIsZero to recognise that a zero sign bit means that we can use a sitofp instead of a uitofp (which is not directly support on pre-AVX512 hardware). While AVX512 does provide support for uitofp, the conversion to sitofp should not cause any regressions. Differential Revision: https://reviews.llvm.org/D24343 llvm-svn: 281852
