--- Comment #10 from Adrian Prantl <aprantl at apple.com> ---
Unfortunately I had to revert this change for now, because it breaks the
following testcase:

$ cat test.ll
%foo = type { void (i32*)* }
@global_initializer = internal constant %foo { void (i32*)* @bar }

define internal void @bar(i32*) {
 ret void
$ llvm-link some-empty-file.ll test.ll |llvm-dis

This causes “bar” (which is only referenced by a not-yet-linked global
initializer) to be removed.
