[PATCH] D85985: [MSAN] Convert ActualFnStart to be a particular Instruction *, not BB

[Gui Andrade via Phabricator via llvm-commits]

guiand updated this revision to Diff 285755.
guiand added a comment.

Move `removeUnreachableBlocks` before inserting the prologue. This makes sure there's no issue with the `ActualFnStart` instruction being deleted before the visitor loop.
