Subject: [PATCH] [NFC] Use opaqueptr in
 llvm/test/Transforms/SimplifyCFG/preserve-llvm-loop-metadata.ll

Use opaqueptr for test case
llvm/test/Transforms/SimplifyCFG/preserve-llvm-loop-metadata.ll.

- Adjust variable number accordingly since bitcast between different pointer
  types are not necessary.
