In order to achieve sound caching, plugin loader double checks the plugin loaded is the same as what dependency scanner sees during compilation. However, user can pass a non-existing macro plugin to the compiler and that should trigger a warning during compilation. Improve the plugin verification to handle the case where the plugin is passed but missing on the file system. rdar://172930632
