<summary>Changes</summary>
To follow-up on a06be8a2 (SLP/RISCV: add negative test for lrint), add a negative test for llvm.llrint as well, and increase the coverage to cover vectors of length 2, 4, and 8, in preparation to get SLPVectorizer to vectorize both lrint and llrint: this is now possible with the recent change 98c90a13 (ISel: introduce vector ISD::LRINT, ISD::LLRINT; custom RISCV lowering).
