test commit: [bd1be8a](https://github.com/llvm/llvm-project/commit/bd1be8a242384d98ef2087f4571b464e01501f5a)
step to reproduce:
`
mlir-opt test.mlir --remove-dead-values
`
test case:
```
module {
func.func private @example(%arg0: tensor<4x4xf32>) -> tensor<4x4xi1> {
llvm.unreachable
}
func.func private @main(%arg0: tensor<4x4xf32>) {
%0 = call @example(%arg0) : (tensor<4x4xf32>) -> tensor<4x4xi1>
llvm.return
}
}
```
Crash backtrace:
```
mlir-opt: /home/workdir/llvm-project/llvm/include/llvm/ADT/BitVector.h:450: bool llvm::BitVector::operator[](unsigned int) const: Assertion `Idx < Size && "Out-of-bounds Bit access."' failed.
