blockaddresses do not participate in the call graph since the only
instructions that use them must all return to someplace within the
current function. And passes cannot retrieve a function address from a
blockaddress.

This was suggested by efriedma in D58260 <https://reviews.llvm.org/D58260>.

Fixes PR50881.
