[mlir] allow function type cloning to fail (#136300)

`FunctionOpInterface` assumed the fact that the function type (attribute
of the operation) can be cloned with arbirary lists of function
arguments and results to support argument and result list mutation. This
is not always correct, in particular, LLVM dialect functions require
exactly one result making it impossible to erase the result.

Allow function type cloning to fail and propagate this failure through
various APIs that use it. The common assumption is that existing IR has
not been modified.

Fixes #131142.

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.

Getting in touch
