The original revision is in Patchset 3.
Four bugs were fixed:
1. JoinEntryInstr::SuccessorCount() is not the correct way to get the
number of successor blocks from the Join block;
JoinEntryInstr::last_instruction()->SuccessorCount() must be used
instead.
2. BitVector::Equals() was non-deterministically returning 'false'
for equal vectors.
3. All blocks need to be processed at least once during the Analysis
phase (not only in the SaveResults phase).
4. We were not removing write barriers from StoreIndexed instructions,
even though we had support for it.
This reverts commit 7fd8ad5a2d.
