mlir-opt version: 22.1.0-rc1
1mlir-opt crashes with an assertion failure when processing a `spirv.CompositeConstruct` operation. The crash occurs because the pass internally casts operand types to `spirv::CompositeType`, but the operand types do not satisfy this assumption, causing a hard abort.
```
mlir-opt test.mlir
```
```
module {
func.func @main() {
%0 = vector.constant_mask [1, 1] : vector<2x2xi1>
%1 = smt.declare_fun : !smt.sort<"uninterpreted0">
%2 = spirv.CompositeConstruct %0, %0 : (vector<2x2xi1>, vector<2x2xi1>) -> vector<2x4xi1>
return
}
}
```
```
mlir-opt: llvm-project-llvmorg-22.1.0-rc1/llvm/include/llvm/Support/Casting.h:560: decltype(auto) llvm::cast(const From&) [with To = mlir::spirv::CompositeType; From = mlir::Type]: Assertion `isa<To>(Val) && "cast<Ty>() argument of incompatible type!"' failed.
