MLIR Program:
```mlir
module {
func.func @m(%arg0: index, %arg1: index) {
%cst = arith.constant dense<true> : vector<[4]xi1>
%6 = llvm.mlir.constant(1 : index) : i64
%107 = llvm.alloca %6 x vector<[4]xi1> : (i64) -> !llvm.ptr
llvm.store %cst, %107 : vector<[4]xi1>, !llvm.ptr
return
}
}
```
Reproduce Command: `mlir-opt -mem2reg a.mlir`
StackTrace:
```
LLVM ERROR: Cannot implicitly convert a scalable size to a fixed-width size in `TypeSize::operator ScalarTy()`
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace and instructions to reproduce the bug.
