  Log Message:
  -----------
  [RISCV] Use TU policy for C reduction intrinsics. (#93970)

The C intrinsics should allow a value to be specified for the upper
elements.

This used to work before https://reviews.llvm.org/D146752 which should
have only changed the behavior for the autovectorizer. It clearly
changed all reductions.
