[mlir][IR] Add `VectorTypeElementInterface` with `!llvm.ptr` (#133455)

This commit extends the MLIR vector type to support pointer-like types
such as `!llvm.ptr` and `!ptr.ptr`, as indicated by the newly added
`VectorTypeElementInterface`. This makes the LLVM dialect closer to LLVM
IR. LLVM IR already supports pointers as vector element type.

Only integers, floats, pointers and index are valid vector element types
for now. Additional vector element types may be added in the future
after further discussions. The interface is still evolving and may
eventually turn into one of the alternatives that were discussed on the
RFC.

This commit also disallows `!llvm.ptr` as an element type of
`!llvm.vec`. This type exists due to limitations of the MLIR vector
type.

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

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.

Getting the Source Code and Building LLVM

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.
