This PR does - fix some bugs to support masked load/store, - refine frontend, and support the `and` and `or` syntax in mask(by extending the BoolOp in python ast.visitor), e.g. `tl.store(..., mask=offset<n and other_conditions)`, - add `arith.cmpI` and `arith.cmpF` op conversion in backend(required by mask), - add more test cases in vecadd.
