[CIR] Assertion failure on alias replacement in clamr_cpuonly.cpp

[rafasumi]

I got the following failure when trying to build clamr_cpuonly.cpp, from the Multisource benchmark in the llvm-test-suite:

clang++: /home/rafael/Git/clangir/mlir/lib/IR/Operation.cpp:563: void mlir::Operation::moveBefore(Block *, llvm::iplist<Operation>::iterator): Assertion `getBlock() && "cannot move an operation that isn't contained in a block"' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
