[PATCH] D76812: [X86] Add Indirect Thunk Support to X86 to mitigate Load Value Injection (LVI) [3/3]

@craig.topper I think that removing spurious MBBs is not really necessary because the emitted machine code doesn't contain the spurious MBBs, from what I have observed. I added the check anyways, if only because others may look at this discrepancy and have the same question.
