>> Could I have a review of this patch - this is just a trivial refactoring with some cleanups for `nativeInst_riscv.h/cpp` using `Assembler::extract()` with raw bits, by adding `extract_rs1`, `extract_rs2`, `extract_rd`, `extract_opcode`, and `extract_funct3` to make the code cleaner and conciser. Tested hotspot tier1 on Qemu with no other errors found.
