Fix disassembling of TIC6X parallel instructions where the previous fetch packet ended with a 32-bit insn.
PR 21056 opcodes * tic6x-dis.c (print_insn_tic6x): Correct displaying of parallel instructions when the previous fetch packet ends with a 32-bit instruction. gas * testsuite/gas/tic6x/insns16-parallel.s: New test case. * testsuite/gas/tic6x/insns16-parallel.d: New test driver.
