Jakub Kuderski 555e41bbf2 [AliasSet] Fix UnknownInstructions printing ...

Summary:
AliasSet::print uses `I->printAsOperand` to print UnknownInstructions. The problem is that not all UnknownInstructions have names (e.g. call instructions). When such instructions are printed, they appear as `<badref>` in AliasSets, which is very confusing, as the values are perfectly valid.

This patch fixes that by printing UnknownInstructions without a name using `print` instead of `printAsOperand`.
