Chandler Carruth 6f20c61e07 Don't default the *cached* list of targets to build to an explicit list
of the targets we know about. Because this is cached, rebuilds won't
detect when new targets show up. It's also a bit simpler to just say
"all". If users want to restrict the target set, they can still do so,
and then the cache will preserve what they have explicitly set this
field to.
