[libc++] Avoid destructor call for error_category singletons When a handle to an error_category singleton object is used during the termination phase of a program, the destruction of the error_category object may have occurred prior to execution of the current destructor or function registered with atexit, because the singleton object may have been constructed after the corresponding initialization or call to atexit. For example, the updated tests from this patch will fail if using a libc++ built using a compiler that updates the vtable of the object on destruction. This patch attempts to avoid the issue by causing the destructor to not be called in the style of ResourceInitHelper in src/experimental/memory_resource.cpp. This approach might not work if object lifetime is strictly enforced.

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.
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.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
