[polly] Assertion `C1->getType() == C2->getType() && "Operand types in binary constant expression should match

[tpgxyz]

Hi,

i'm trying to compile kernel-6.0.10 with LLVM toolchain 15.0.6 with polly enabled on AArch64:

clang: /builddir/build/BUILD/llvm-project-15.0.6.src/llvm/lib/IR/Constants.cpp:2272: static llvm::Constant *llvm::ConstantExpr::get(unsigned int, llvm::Constant *, llvm::Constant *, unsigned int, llvm::Type *): Assertion `C1->getType() == C2->getType() && "Operand types in binary constant expression should match"' 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.
