Hi!

The following starts to crash with this patch, and it still crashes on current top of tree 036aeac36c <https://reviews.llvm.org/rG036aeac36c00f4390e861118f536150b366beaaf>:

  opt -passes='require<ir-similarity>' -o /dev/null bbi-68950.ll

We get

  opt: ../include/llvm/Support/Casting.h:269: typename cast_retty<X, Y *>::ret_type llvm::cast(Y *) [X = llvm::Instruction, Y = llvm::Value]: Assertion `isa<X>(Val) && "cast<Ty>() argument of incompatible type!"' failed.
  PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
