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:
PR libstdc++/103453
* config/allocator/malloc_allocator_base.h
(_GLIBCXX_SANITIZE_STD_ALLOCATOR): Define for Clang.
* config/allocator/new_allocator_base.h
(_GLIBCXX_SANITIZE_STD_ALLOCATOR): Likewise.
(cherry picked from commit cca6090b13ab503bef1cfa327e2d107789d6bd30)
