[rust] Changes needed for 'x86_64-fortanix-unknown-sgx' nightly target.

Code is guarded via defines to enable only if 'RUST_SGX' is present.

Main logic is in libunwind/src/AddressSpace.hpp
We use 6 symbols to figure out where eh_frame / eh_frame_hdr is at runtime when loaded in an SGX enclave. (EH symbols + IMAGE base)
These are set by 'fortanix-sgx-tools'.

As notes:
- Target above at the moment uses a pre-compiled libunwind.a from forked repo.
- Goal of these changes is to use official llvm with patch.
- Changes in rust-lang to use this are planned if/when this is accepted.
- Ticket: fortanix/rust-sgx#174
- Original ported changes: llvm/llvm-project@release/5.x...fortanix:release/5.x

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.

Getting the Source Code and Building LLVM

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.

Getting in touch

Join the LLVM Discourse forums, Discord chat, or #llvm IRC channel on OFTC.

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