The test added in #155573 assumes the compiler defaults to the current default
of C++17. If the compiler is changed to default to C++20, the test fails
because the expected warnings about a construct being a C++20 extension are no
longer emitted. This change fixes up the test to work in either C++17 or C++20
mode by disabling the warning and removing the check for it as this is not what
is being tested here.

Subject: [PATCH] Fixup test added in #155573 to work when the compiler
defaults to C++20.
