Experienced a crash with clang 20.1.8 while compiling gsl 2.7 or 2.7.1. Only crashes with an optimized build. Debug builds do not exhibit this crash
Stacktrace:
```
clang: llvm/lib/Transforms/Vectorize/SLPVectorizer.cpp:3637: llvm::slpvectorizer::BoUpSLP::TreeEntry* llvm::slpvectorizer::BoUpSLP::newTreeEntry(llvm::ArrayRef<llvm::Value*>, TreeEntry::EntryState, std::optional<ScheduleData*>, const {anonymous}::InstructionsState&, const EdgeInfo&, llvm::ArrayRef<int>, llvm::ArrayRef<unsigned int>): Assertion `(hasFullVectorsOrPowerOf2(*TTI, getValueType(VL.front()), VL.size()) || ReuseShuffleIndices.empty()) && "Reshuffling scalars not yet supported for nodes with padding"' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
