sh: Add a simple code dumper for SUPERH32 show_regs().

This implements a simple show_code() that is in turn plugged in to show_regs() to provide minimal code dumping at the end of the trace. Built on top of a simple instruction disassembler derived from the binutils opcode table. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
