X86: Add baseline test for computeKnownBits poison+vector handling Currently computeKnownBits is too conservative with poison inputs. https://invent.kde.org/qt/clang/llvm-project/-/commit/5312a830d52769e8301be5deb5eec61bea1d2988 Git commit bea6832651eda09f30f54aeb3ce77965158874f6 by Matt Arsenault on 07/08/2026 at 20:55.. DAG: Skip poison elements in BUILD_VECTOR computeKnownBits This defends against regressions in future patches. Copies the logic from the IR version of computeKnownBits's handling of ConstantVector. I'm not sure why the IR version doesn't directly return a value for poison, but this follows suit.
