arch/tile: Shrink the tile-opcode files considerably. 



The C file (tile-desc_{32,64}.c) was about 300KB before this change,
and is now shrunk down to 100K.  The original file included support
for BFD in the binutils toolchain, which is not necessary in the
kernel; the kernel version only needs to include enough support to
enable the single-stepper and backtracer.
