add bytevector ops to the vm

Browse source 
* libguile/instructions.h (SCM_VM_NUM_INSTRUCTIONS): Enlarge to 255. Not
  sure what performance effects this will have.

* libguile/vm-engine.c: Add new error case, vm_error_not_a_bytevector.

* libguile/vm-engine.h: Don't assign specific registers for i386. Having
  added the new VM vector ops, GCC 4.4 is erroring for me now.

* libguile/vm-i-scheme.c: Add bytevector-specific ops to the VM.
  We don't actually use them yet, though.
