[llvm] Initialize aarch64-cond-br-tuning pass (PR #132087)

[Shubham Sandeep Rastogi via llvm-commits]

https://github.com/rastogishubham created https://github.com/llvm/llvm-project/pull/132087

The call to the initializeAArch64CondBrTuningPass function is missing in the AArch64TargetMachine LLVMInitializeAArch64Target function.

This means that the pass is not in the pass registry and options such as -run-pass=aarch64-cond-br-tuning and
-stop-after=aarch64-cond-br-tuning cannot be used. This patch fixes that issue.
