[clang] [clang-repl] [test] Make an XFAIL more precise (PR #70991)

[Martin Storsjö via cfe-commits]

https://github.com/mstorsjo created https://github.com/llvm/llvm-project/pull/70991

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
