Philip Pfaffe 19045617b3 [PM] Enable registration of out-of-tree passes with PassBuilder ... Summary: This patch adds a callback registration API to the PassBuilder, enabling registering out-of-tree passes with it. Through the Callback API, callers may register callbacks with the various stages at which passes are added into pass managers, including parsing of a pass pipeline as well as at extension points within the default -O pipelines. Registering utilities like `require<>` and `invalidate<>` needs to be handled manually by the caller, but a helper is provided. Additionally, adding passes at pipeline extension points is exposed through the opt tool. This patch adds a `-passes-ep-X` commandline option for every extension point X, which opt parses into pipelines inserted into that extension point.
