Remove unnecessary work in dominators computation.
Also rename 'undomid' to better indicate how it is being used.
This fixes a performance problem with the dominators computation for
some pathological cases, in one case reducing the time to compute
dominators from 10 minutes down to a few seconds.
Bug: 33957507
Test: m ahat-test
Test: manually verify overview and rooted numbers are unchanged for a
reasonably complex heap dump.
