[NIOS2] Fix disassembly of br.n instruction.
The code was checking wrong bit for sign extension. It caused it to zero-extend instead of sign-extend the immediate value. 2021-03-25 Abid Qadeer <abidh@codesourcery.com> opcodes/ * nios2-dis.c (nios2_print_insn_arg): Fix sign extension of immediate in br.n instruction. gas/ * testsuite/gas/nios2/brn.s: New. * testsuite/gas/nios2/brn.d: New.
