4464646efb [Triton-MLIR][BACKEND] Fix masked load store op vector size (#785)
Correct the Load/Store Op's vector size with the mask's alignment
correctly considered.

Some cases:

```mlir
// num_warp = 2
// block_size = 128
func @vecadd_mask_align_16(%a_ptr: !tt.ptr<f32> {tt.divisibility = 16 : i32}, %b_ptr: !tt.ptr<f32> {tt.divisibility = 16 : i32}, 
  %out_ptr: !tt.ptr<f32> {tt.divisibility = 16 : i32}, %n_elements: i32 {tt.divisibility = 16 : i32}) {
    // mask = make_range(128) < n_element
}
```
This should get the vec=2 `ld`/`st` instructions.

While the following example

```mlir
// num_warp = 2
// block_size = 128
func @vecadd_mask_align_16(%a_ptr: !tt.ptr<f32> {tt.divisibility = 16 : i32}, %b_ptr: !tt.ptr<f32> {tt.divisibility = 16 : i32}, 
  %out_ptr: !tt.ptr<f32> {tt.divisibility = 16 : i32}, %n_elements: i32) {
    // mask = make_range(128) < n_element
}
```
it should get the vec=1 `ld`/`st` instructions.

This PR adds basic support for scalar-type inputs to some ops (cast and pointer arithmetics) for Triton-MLIR. Also renames getelementptr -> addptr
