  Changed paths:
    M llvm/lib/IR/Verifier.cpp
    M llvm/unittests/IR/VerifierTest.cpp

  Log Message:
  [Verifier] Iteratively traverse all indirect users.

The recursive implementation can run into stack overflows, e.g. like in PR52844.

The order the users are visited changes, but for the current use case
this only impacts the order error messages are emitted.
