    libstdc++: Make Asan detection work for Clang [PR103453]

    Clang doesn't define __SANITIZE_ADDRESS__ so use its __has_feature check
    to detect Asan instead.

    libstdc++-v3/ChangeLog:

            * config/allocator/new_allocator_base.h
            (_GLIBCXX_SANITIZE_STD_ALLOCATOR): Likewise.
