5f202fe5c1 [Language] Initial version of tilelang frontend v2 (#1120)
* tilelang frontend v2

* syntax sugar: defining a local var by annotation

* [Refactor] fix type linting warning like `T.float32`

* Add tl.local_var_init for new tl.float32

* allow passing default argument as function annotation

* allow default arguments as annotation

* fix lint error

* minor fix

* [Refactor] refactor tilelang.jit and tilelang.autotune

* minor fix

* minor fix

* minor fix

* fix metal get function name

* add par_compile impl and tests

* Type consistency on tvm datatype
1. isinstance(tl.float32, tvm.DataType) == True
2. Allow `tl.float32` as function annotations
3. Allow `tl.float32` as argument to be passed to `tl.alloc` or other functions

* fix lint error

* add more warning in frontend

* update tvm version

* Minor fix on tvm_ffi annotations

* add document and examples

* fix lint error

* Simplify index calculations in example_chunk_o_bwd.py

Refactor index calculations for dg_last_fragment assignment.

* minor fix

* lint fix
