This PR makes verification of .debug_names acceleration table multithreaded. In local testing it improves verification of clang .debug_names from four minutes to under a minute. This PR relies on a current mechanism of extracting DIEs into a vector. Future improvements can include creating API to extract one DIE at a time, or grouping Entires into buckets by CUs and extracting before parallel step.

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.
