Test commit: https://github.com/llvm/llvm-project/commit/9e91725fd4d4ee30e98ab2682f93b423590a4ade
Steps to reproduce:
```shell
mlir-opt test.mlir -test-symbol-uses
```
Test case:
```mlir
module attributes {gpu.container_module} {
func.func @main(%arg0: tensor<4x4xf32>) attributes {pattern_driver_all_erased = true, pattern_driver_changed = false} {
%0 = llvm.mlir.constant(128 : index) : i64
%1 = llvm.mlir.constant(1 : index) : i64
%2 = builtin.unrealized_conversion_cast %1 : i64 to index
%3 = builtin.unrealized_conversion_cast %0 : i64 to index
%4 = gpu.wait async
%5 = gpu.launch_func async [%4] @main_kernel::@main_kernel blocks in (%2, %2, %2) threads in (%2, %2, %2) args(%3 : index)
return
}
gpu.module @main_kernel {
gpu.func @main_kernel(%arg0: index) kernel attributes {known_block_size = array<i32: 1, 1, 1>} {
gpu.return
}
}
}
```
