(init_opcode_tables): Delete cpu_type_map, call
arc_get_opcode_mach instead.
(arc_common): Delete non-ELF stuff. Require leading '.' in .data.
(md_apply_fix): Delete non-ELF stuff.
Disable special handling of limm values, treat them normally.
(get_arc_exp_reloc_type): New argument `data_p'. Callers updated.
(md_assemble): All limm operands must be output by gas, the opcode
insertion routines cannot be used (they don't do anything and we're
using implicit addends now so we need to output something).
* config/tc-arc.h (FAKE_LABEL_NAME): Define.
