API Header/Implementation mismatch

[Naville]

llvm/IR/Verifier.h

llvm/IR/Verifier.cpp

In the header we have:

bool verifyModule(const Module &M, raw_ostream *OS = nullptr,
                  bool *BrokenDebugInfo = nullptr);
bool verifyModule(bool &BrokenDebugInfo, const Module &M, raw_ostream *OS);

But only the former is actually implemented in the cpp, resulting in:

Undefined symbols for architecture arm64:
  "llvm::verifyModule(bool&, llvm::Module const&, llvm::raw_ostream*)", referenced from:

Seems at least a issue since LLVM 11, didn't bother to look furthur

Date back to e365618 where the declaration is added without implementation?
