Add dependancies for itbl files to mips target. * as.c: Add itbl support. Add new option "--insttbl" for dynamically extending instruction set. * as.h: Declare insttbl_file_name; the name of file defining extensions to the basic instruction set * configure.in, configure: Add itbl-parse.o, itbl-lex.o, and itbl-ops.o to extra_objects for mips configuration. Add include file link from itbl-cpu.h to config/itbl-${target_cpu_type}.h. * config/tc-mips.c: Allow copz instructions. Add notes for future additions to the itbl support. Add debug macros.
