  Changed paths:
    M llvm/lib/Transforms/Vectorize/SLPVectorizer.cpp
    A llvm/test/Transforms/SLPVectorizer/RISCV/reduced-copyable-element.ll

  Log Message:
  -----------
  [SLP]Do not remove reduced value, if it is a copyable

If the value is checked for the reduction and it is a copyable element
in a root node, it should not be deleted, since it may still be used
after vectorization.

Fixes #155512
