[PATCH] Use properly aligned pointers for empty/tombstone DenseMap keys.

[Alexey Samsonov]

Implement a limited fix to the problem, suggested by Richard Smith:
redefine DenseMapInfo<AssertingVH<T>>::isEqual to ensure it doesn't
perform pointer downcasts: fake pointer values for empty/tombstone keys
may not be properly aligned.
