[RFC PATCH bpf-next 3/3] bpf, riscv: Use compressed instructions in the rv64 JIT

This patch uses the RVC support and encodings from bpf_jit.h to optimize the rv64 jit. The optimizations work by replacing emit(rv_X(...)) with a call to a helper function emit_X, which will emit a compressed version of the instruction when possible, and when RVC is enabled. The JIT continues to
