A bug in the RISC-V vector block move implementation has been fixed, ensuring that the memcpy path is correctly gated by the riscv_memcpy_size_threshold. Previously, this threshold was incorrectly gated by riscv_memmove_size_threshold, leading to the memcpy path only being honored under specific, unrelated conditions related to memmove settings.
