[Bug libstdc++/34797] New: [parallel mode] Settings are separated for each compilation unit

["singler at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

In settings.h, the Settings class (containing only static variables) is
encapsulated in an anonymous namespace. This makes the linker think of a
distinct class for each compilation unit. As as result, settings changed in one
.cpp file won't affect code from another .cpp file, although they should have
global effect.
