Let's put a warning here, at least until we see if people need this.  A default
Relocation mode of NONE is unsafe, unless we know that people really will have
64-bit integers that are not coming from pointers.  Since the argument has
integer type, rather than pointer type, it might be OK to have that default mode
here, but I was intending for all relocation modes to be explicit.
