arc: Replace ARC_SHORT macro with arc_opcode_len function
In preparation for moving to a world where arc instructions can be 2, 4,
6, or 8 bytes in length, replace the ARC_SHORT macro (which is either
true of false) with an arc_opcode_len function that returns a length in
bytes.
There should be no functional change after this commit.
gas/ChangeLog:
* config/tc-arc.c (assemble_insn): Replace use of ARC_SHORT with
arc_opcode_len.
include/ChangeLog:
* opcode/arc.h (arc_opcode_len): Declare.
(ARC_SHORT): Delete.
opcodes/ChangeLog:
* arc-dis.c (find_format_from_table): Replace use of ARC_SHORT
with arc_opcode_len.
(find_format_long_instructions): Likewise.
* arc-opc.c (arc_opcode_len): New function.
