[mlir][llvm][x86vector] One-to-one intrinsic op interface (#140055)

Adds an LLVMIR op interface that can used by external operations to
model LLVM intrinsics. Related 'op to llvm.call_intrinsic' rewriter
helper is moved into common LLVM conversion patterns. The x86vector
dialect is refactored to use the new common abstraction.

The one-to-one intrinsic op is tied to LLVM intrinsic call semantics.
Thus, the op interface, previously defined as a part of x86vector
dialect, is moved into the LLVMIR interfaces to allow other low-level
dialects to define operations abstracting specific intrinsic semantics
while minimizing infrastructure duplication.

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.
