fixup! fixup! [GlobalISel] Always direct-call IFuncs and Aliases (#74902)

Apparently some BOLT bots build with a pre-installed system clang, and others
use the just-built one. These two clangs now behave slightly differently when
it comes to ifunc codegen after #74902

Change the test to accept both patterns.
