add bytevector ops to the vm
* 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.
