Joao Moreira 417137b6f5 [X86] Make ENDBR instruction a scheduling boundary
Instructions should not be scheduled across ENDBR instructions, as this would result in the ENDBR being displaced, breaking the parity needed for the Indirect Branch Tracking feature of CET.

Currently, the X86IndirectBranchTracking pass is later than the instruction scheduling in the pipeline, what causes the bug to be unnoticeable and very hard (if not unfeasible) to be triggered while compiling C files with the standard LLVM setup. Yet, for correctness and to prevent issues in future changes, the compiler should prevent the such scheduling.

The LLVM Compiler Infrastructure
================================

This directory and its subdirectories contain source code for LLVM,
a toolkit for the construction of highly optimized compilers,
optimizers, and runtime environments.

LLVM is open source software. You may freely distribute it under the terms of
the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.

If you are writing a package for LLVM, see docs/Packaging.rst for our
suggestions.
