Review comment:
Sure. It may cause problems when fusing i32 indices with i64 indices. A
simplified example:
```
i64_2 = tvm.tir.const(2, "int64")
i64_4 = tvm.tir.const(4, "int64")
i32_2 = tvm.tir.const(2, "int32")
a = te.placeholder((i64_4, i64_4), "a")
b = te.compute((i64_2, i64_2), lambda i, j: a[i + 2, j + 2])
c = te.compute((i32_2, i32_2), lambda i, j: b[i, j] + 1)
```
When fusing `b` into `c`, the i64 variables in `b` are replaced by i32
expressions in `c`, which does not make sense.
