mlir-opt version: 22.1.0-rc1
Running mlir-opt on the following MLIR causes an assertion failure in Type::getIntOrFloatBitWidth()
```
module {
func.func @main() {
%0 = gpu.subgroup_size : index
%1 = arm_sme.get_tile : vector<[16]x[16]xi8>
%2 = smt.forall ["x"] {
^bb0(%arg0: !smt.int):
%c1 = smt.int.constant 1
%3 = smt.int.add %arg0, %c1
%4 = smt.eq %3, %arg0 : !smt.int
smt.yield %4 : !smt.bool
}
%5 = math.ctpop %1 : vector<[16]x[16]xi8>
%6 = amdgpu.dpp %5 %1 row_shl {permArgument = 1 : i32, row_mask = 15 : i32, bank_mask = 15 : i32} : vector<[16]x[16]xi8>
return
}
}
```
