[PATCH] RISC-V: Add split pattern to generate SFB instructions. [PR113095]

Since the match.pd transforms (zero_one == 0) ? y : z y, into ((typeof(y))zero_one * z) y. Add splitters to recongize this expression to generate SFB instructions. gcc/ChangeLog: PR target/113095 * config/riscv/sfb.md: New splitters to rewrite single bit sign extension as
