This pull request adds an optimized implementation of the
Lt128operator for RVV targets. The new implementation is synthesized using a program synthesizer.The main computations use LMUL 1/8, which is usually more efficient than vector groups (LMUL > 1) and can outperform full vector registers (LMUL = 1) on some microarchitectures.
