[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.

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.
