Martin Storsjö 2c4f938f1c Reapply #2 [clang-repl] [test] Make an XFAIL more precise (#71168 )

The const.cpp testcase fails when running in MSVC mode, while it does
succeed in MinGW mode.

In MSVC mode, there are more constructor invocations than expected, as
the printout looks like this:

    A(1), this = 0000025597930000
    A(1), this = 0000025597930000
    f: this = 0000025597930000, val = 1
    A(1), this = 0000025597930000
    f: this = 0000025597930000, val = 1
    ~A, this = 0000025597930000, val = 1
    ~A, this = 0000025597930000, val = 1
    ~A, this = 0000025597930000, val = 1

While the expected printout looks like this:

    A(1), this = 000002C903E10000
    f: this = 000002C903E10000, val = 1
    f: this = 000002C903E10000, val = 1
    ~A, this = 000002C903E10000, val = 1

Reapplying #70991 with the XFAIL changed to check the host triple, not
the target triple. On an MSVC based build of Clang, but with the default
target triple set to PS4/PS5, we will still see the failure. And a Linux
based build of Clang that targets PS4/PS5 won't see the issue.

===============================
 lit - A Software Testing Tool
===============================

About
=====

*lit* is a portable tool for executing LLVM and Clang style test suites,
summarizing their results, and providing indication of failures. *lit* is
designed to be a lightweight testing tool with as simple a user interface as
possible.


Features
========

 * Portable!
 * Flexible test discovery.
 * Parallel test execution.
 * Support for multiple test formats and test suite designs.


Documentation
=============

The official *lit* documentation is in the man page, available online at the LLVM
Command Guide: http://llvm.org/cmds/lit.html.


Source
======

The *lit* source is available as part of LLVM, in the LLVM source repository:
https://github.com/llvm/llvm-project/tree/main/llvm/utils/lit


Contributing to lit
===================

Please browse the issues labeled *tools:llvm-lit* in LLVM's issue tracker for
ideas on what to work on:
https://github.com/llvm/llvm-project/labels/tools%3Allvm-lit

Before submitting patches, run the test suite to ensure nothing has regressed::

    # From within your LLVM source directory.
    utils/lit/lit.py \
        --path /path/to/your/llvm/build/bin \
        utils/lit/tests

Note that lit's tests depend on ``not`` and ``FileCheck``, LLVM utilities.
You will need to have built LLVM tools in order to run lit's test suite
successfully.

You'll also want to confirm that lit continues to work when testing LLVM.
Follow the instructions in http://llvm.org/docs/TestingGuide.html to run the
regression test suite:

    make check-llvm

And be sure to run the llvm-lit wrapper script as well:

    /path/to/your/llvm/build/bin/llvm-lit utils/lit/tests

Finally, make sure lit works when installed via setuptools:

    python utils/lit/setup.py install
    lit --path /path/to/your/llvm/build/bin utils/lit/tests
