Dan Gohman f844b3b227 Remove the code from Function::dropAllReferences which replaced ...

uses of the function's blocks with undef. This code isn't needed,
because BasicBlock's destructor handles such uses. Also, undef isn't
correct, since blockaddresses may still be used for comparisons
with null.
