Chris Lattner 50b136dae9 add bitcode reader support for blockaddress. We can now fully
round trip blockaddress through .ll and .bc files, so add a testcase.

There are still a bunch of places in the optimizer and other places
that need to be updated to work with these constructs, but at least
the basics are in now.
