[CIR] Defer declarations and tentative definitions (#141700)

This change adds code to defer emitting declarations and tentative
definitions until they are referenced or trigger by a call to
CompleteTentativeDefinition. This is needed to avoid premature handling
of declarations and definitions that might not be referenced in the
current translation unit. It also avoids incorrectly adding an
initializer to external declarations.

This change also updates the way the insertion location for globals is
chosen so that all globals will be emitted together at the top of the
module. This makes no functional difference, but it is very useful for
writing sensible tests.

Some tests are modified in this change to reorder global variables so
that they can be checked in the order in which they will be emitted.

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.
