[BOLT] Handle generation of compare and jump sequences (#131949)
This patch fixes the following two issues with the createCmpJE for
AArch64:
1. Avoids overwriting the value of the input register RegNo by use XZR
as the destination register.
   subs xzr, RegNo, #Imm
   which is equivalent to a simple
   cmp RegNo, #Imm
2. The immediate operand to the Bcc instruction must be EQ instead of
#Imm.

This patch also adds a new function for createCmpJNE and unit tests for
the both createCmpJE and createCmpJNE for X86 and AArch64.

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.
