Speed up `HGraph::BuildDominatorTree()`.
Add some functions from `BitVector` to `BitVectorView<>`
and use this to speed up `HGraph::BuildDominatorTree()`.
Also clean up code sinking. This was a missed opportunity in
https://android-review.googlesource.com/3500455 .
Test: m test-art-host-gtest
Test: testrunner.py --host --optimizing
