Crashes on opt if assign-guid pass is missing, for any IR input.
The pass should fail gracefully, possibly with reportFatalUsageError(), rather than asserting.
$ opt --mtriple=x86_64-unknown-linux-gnu --passes=ctx-prof-flatten-prethinlink -S test.ir
opt: llvm-project/llvm/lib/Analysis/CtxProfAnalysis.cpp:444: static llvm::GlobalValue::GUID llvm::AssignGUIDPass::getGUID(const llvm::Function&): Assertion `MD && "guid not found for defined function"' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace and instructions to reproduce the bug.
