[lit] Add support for readfile to external shell

This patch adds support for the new lit %{readfile:<filename>}
substitution to the external shell. The implementation currently just
appends some test commands to ensure the file exists and uses a subshell
with cat. This is intended to enable running tests using the
substitution in the external shell before we fully switch over to the
internal shell.

This code is designed to be temporary with us deleting it once
everything has migrated over to the internal shell and we are able to
remove the external shell code paths.

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.
