perf python: Allow checking for the existence of warning options in clang

Browse Source 
commit b81162302001f41157f6e93654aaccc30e817e2a upstream.

We'll need to check if an warning option introduced in clang 19 is
available on the clang version being used, so cover the error message
emitted when testing for a -W option.
