Sanjay Patel a75b2d22ae [PatternMatch, InstSimplify] enhance m_AllOnes() to ignore undef elements in vectors ... Loosening the matcher definition reveals a subtle bug in InstSimplify (we should not assume that because an operand constant matches that it's safe to return it as a result). So I'm making that change here too (that diff could be independent, but I'm not sure how to reveal it before the matcher change). This also seems like a good reason to *not* include matchers that capture the value. We don't want to encourage the potential misstep of propagating undef values when it's not allowed/intended. I didn't include the capture variant option here or in the related rL325437 (m_One), but it already exists for other constant matchers. llvm-svn: 325466		2018-02-18 18:05:08 +00:00
