Summary:
Add a new plugin API. This closes the gap between pass registration and out-of-tree passes for the new PassManager.
Unlike with the existing API, interaction with a plugin is always
initiated from the tools perspective. I.e., when a plugin is loaded, it
resolves and calls a well-known symbol `llvmGetPassPluginInfo` to obtain
details about the plugin. The fundamental motivation is to get rid of as
many global constructors as possible. The API exposed by the plugin
info is kept intentionally minimal.
