documentation: Transitivity is not cumulativity
The "transitivity" section mentions cumulativity in a potentially
confusing way. Contrary to the current wording, cumulativity is
not transitivity, but rather a hardware discipline that can be used
to implement transitivity on ARM and PowerPC CPUs. This commit
therefore deletes the mention of cumulativity.
