[clang-repl] Fix OrcRuntime lookup for Solaris and unit tests. (#175435)

The out-of-process execution in the interpreter depends on the orc
runtime. It is generally easy to discover as it is in the clang runtime
path. However, the clang runtime path is relative to clang's resource
directory which is relative to the clang binary. That does not work well
if clang is linked into a different binary which can be in a random
place in the build directory structure.

This patch performs a conservative approach to detect the common
directory structure and correctly infer the paths. That fixes the
out-of-process execution unittests. The patch also contains a small
adjustment for solaris.

Another take on trying to fix the issue uncovered by #175322.

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.
