[ARC] Enhance enter/leave mnemonics.
enter/leave mnemonics are enhanced to not only accept register ranges but also single register (i.e., r13) or even no GPR register at all. gas/ 2017-04-25 Claudiu Zissulescu <claziss@synopsys.com> * testsuite/gas/arc/leave_enter.d: Update test. * testsuite/gas/arc/leave_enter.s: Likewise. opcodes/ 2017-04-25 Claudiu Zissulescu <claziss@synopsys.com> * arc-dis.c (print_insn_arc): Smartly print enter/leave mnemonics. * arc-opc.c (insert_r13el): New function. (R13_EL): Define. * arc-tbl.h: Add new enter/leave variants.
