Remove char->integer from VM

Browse source 
* libguile/vm-engine.c (VM_VALIDATE_CHAR, VM_VALIDATE_STRING)
  (VM_VALIDATE_INDEX): Remove now-unused helpers.
  (vm_engine): Fix position of intrinsics declaration.
  (char->integer): Remove unused opcode.
* libguile/vm.c (vm_error_not_a_char, vm_error_not_a_string)
  (vm_error_out_of_range_uint64): Remove unused decls.
