810ac29c - Reapply "[llvm-exegesis] Implement the loop repetition mode for AArch64" (#155423) (#155589)

Reapply "[llvm-exegesis] Implement the loop repetition mode for AArch64" (#155423) (#155589) This includes two minor fixes: - "Codegen" has been added to the LLVM_LINK_COMPONENTS for AArch64 to prevent a link error, - the test case has been made less strict or fragile by not checking the addresses.
