printing references the symbol table to determine whether the
instruction resides in a block regular instructions or mips16
instructions. However, when the disassembler gets used in other
environments where the symbol table is not present, we no longer
rely in the symbol table, rather, use the low bit of the
instructions address to guess. There should be no change for usage
of the disassembler in host based programse, gdb ,objdump.
