[mlir][ptr] Extend `ptr_add` operation to support shaped operands (#156374)
This patch extends `ptr_add` to work with shaped types with value
semantics, both for the offsets and base.
Concretely this patch makes the following changes:
- Supports scalar-to-scalar, scalar-to-shaped, shaped-to-scalar, and
shaped-to-shaped combinations
- Adds InferTypeOpInterface for automatic result type deduction
- Adds tests for LLVM IR translation with vector operands
Example:
```mlir
func.func @ptr_add_tensor_2d(%ptrs: tensor<4x8x!ptr.ptr<#ptr.generic_space>>, %offsets: tensor<4x8xindex>) -> tensor<4x8x!ptr.ptr<#ptr.generic_space>> {
%res = ptr.ptr_add %ptrs, %offsets : tensor<4x8x!ptr.ptr<#ptr.generic_space>>, tensor<4x8xindex>
%res1 = ptr.ptr_add nuw %ptrs, %offsets : tensor<4x8x!ptr.ptr<#ptr.generic_space>>, tensor<4x8xindex>
return %res : tensor<4x8x!ptr.ptr<#ptr.generic_space>>
}
```
The motivation behind this patch is to lay the groundwork for enabling
`triton` styled loads and stores, and their variants.

Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
Consult the Getting Started with LLVM page for information on building and running LLVM.
For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.
Join the LLVM Discourse forums, Discord chat, LLVM Office Hours or Regular sync-ups.
The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
