Fold expressions on Clang are limited to 256 elements. This causes compilation errors in cases when the amount of elements added exceeds this limit. Side-step the issue by restoring the original trick that would use the std::initializer_list. For the record, in our downstream Clang 16 gives: mlir/include/mlir/IR/Dialect.h:269:23: fatal error: instantiating fold expression with 688 arguments exceeded expression nesting limit of 256 (addType<Args>(), ...); Partially reverts 26d811b3ecd2fa1ca3d9b41e17fb42b8c7ad03d6.

The LLVM Compiler Infrastructure
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.
