[PATCH] D30631: [BPI] Use metadata info before any other heuristics

[David Li via Phabricator via llvm-commits]

Note that it is possible to have some BB to have metadata while others do not (e.g with builtin_expect). Your patch may break in those case when PostDominatebyUnreachable computation is skipped with this change.
