Sanne Wouda 8cf92aa718 [AArch64] Fix save register pairing for Windows AAPCS
Summary:
On Windows, when a function does not have an unwind table (for example, EH
filtering funclets), we don't correctly pair FP and LR to form the frame record
in all circumstances.

Fix this by invalidating a pair when the second register is FP when compiling
for Windows, even when CFI is not needed.

Fixes PR44271 introduced by D65653.

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.
