Lang Hames ad6b1171f3 [ORC][ORC-RT] Add initial native-TLV support to MachOPlatform. 
Adds code to LLVM (MachOPlatform) and the ORC runtime to support native MachO
thread local variables. Adding new TLVs to a JITDylib at runtime is supported.

On the LLVM side MachOPlatform is updated to:

1. Identify thread local variables in the LinkGraph and lower them to GOT
accesses to data in the __thread_data or __thread_bss sections.

2. Merge and report the address range of __thread_data and thread_bss sections
to the runtime.

On the ORC runtime a MachOTLVManager class introduced which records the address
range of thread data/bss sections, and creates thread-local instances from the
initial data on demand. An orc-runtime specific tlv_get_addr implementation is
included which saves all register state then calls the MachOTLVManager to get
the address of the requested variable for the current thread.

The LLVM Compiler Infrastructure
================================

This directory and its subdirectories contain source code for LLVM,
a toolkit for the construction of highly optimized compilers,
optimizers, and runtime environments.

LLVM is open source software. You may freely distribute it under the terms of
the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.

If you are writing a package for LLVM, see docs/Packaging.rst for our
suggestions.
