Reland [Clang][CMake] Support perf, LBR, and Instrument CLANG_BOLT options (#69133)

This reverts commit 6953b367027e4234607a6718a0a1d57eb52ef57e.

Couldn't reproduce cmake issues from any of the affected buildbots:
https://lab.llvm.org/buildbot/#/builders/139/builds/57628
https://lab.llvm.org/buildbot/#/builders/163/builds/50270
https://lab.llvm.org/buildbot/#/builders/223/builds/34823
https://lab.llvm.org/buildbot/#/builders/225/builds/29950
https://lab.llvm.org/buildbot/#/builders/245/builds/19468

A common trait is that these builders don't clean build directory.
Push again and monitor these builders.

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.

For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.
