Merge commit 72a20b8e2987 from llvm git (by Gabriel Baraldi):HEADmain

  [SLPVectorizer] Check std::optional coming out of getPointersDiff (#175784)

  Fixes https://github.com/llvm/llvm-project/issues/175768
  There are other unchecked uses std::optional in this pass but I couldn't
  figure out a test that triggers them

This fixes a clang crash in the SLP vectorizer, hit when building
audio/csound on powerpc64le. The hardened libc++ traps on the disengaged
optional, so clang dies with exit code 133. The second hunk is adapted to
llvm 21, where analyzeConstantStrideCandidate() is still isStridedLoad().
