This fixes an incompatibility when wrapping native 32-bit engines with a userland
engine. The latter always used the 64-bit range function which then used two
32-bit numbers from the underlying engine to fill the 64-bit range, whereas the
native implementation used only one.
Now the selection of the range variant only depends on the requested range. A
32-bit range uses the 32-bit variant (even for 64-bit engines), whereas a
larger range uses the 64-bit variant.
