* %load/x <bit>, <functor-label>, <idx>
This is an indexed load. It uses the contents of the specified index
register to select a bit from an array based at <functor-label>. The
bit is pulled from the addressed functor and loaded into the
destination bit. This function does not do any bounds checking.
