This is just a quick note the let everyone know dyn_cast now works
properly with BasicBlock::iterator's and others. In other words, you can
now do things like this:
for (BasicBlock::iterator I = BB.begin();
PHINode *PN = dyn_cast<PHINode>(I); ++I)
...
instead of this:
for (BasicBlock::iterator I = BB.begin();
PHINode *PN = dyn_cast<PHINode>(&*I); ++I)
...
This was a long standing problem that I finally got around to fixing. Now
you should almost never need to use "&*" anymore.
