Hi there,
I tried to parse a TVMScript with long vector data type as the following case
```python
@T.prim_func
def func():
A = T.var("int32x32")
B = T.reinterpret(A, dtype="int8x128")
f_script = func.script()
f_roundtrip = script.from_source(f_script)
```
It generates TVMScript as below
```python
@T.prim_func
def main():
A = T.int32x32()
B: T.int8x128 = T.reinterpret("int8x128", A)
T.evaluate(0)
```
But an error occured during parsing because of definiton of T.int8x128 is
missing
```
--> <str>:6:8
|
6 | B: T.int8x128 = T.reinterpret("int8x128", A)
| ^^^^^^^^^^
```
The current definition of vector dtype cannot cover all types in actual
use，shall we consider changing the printing method of vector dtypes to
something like T.vec_type("int8", 128)?
