[PATCH] D39764: [cfi-verify] Made FileAnalysis operate on a GraphResult rather than build one and validate it.

[Mitch Phillips via Phabricator via llvm-commits]

hctim created this revision.

Refactors the behaviour of building graphs out of FileAnalysis, allowing for analysis of the GraphResult by the callee without having to rebuild the graph. Means when we want to analyse the constructed graph (planned for later revisions), we don't do repeated work.

Also makes CFI verification in FileAnalysis now return an enum that allows us to differentiate **why** something failed, not just that it did/didn't fail.
