Split up `apply` into the following steps:

- `findUnreachable`
- `createStableOrder`
- `preAssignWeights`
- `canApplyInference`
- `extractProfile`
- `verifyProfileConsistency`

With some specializations, `apply` should apply to BOLT stale profile matching
(D144500 <https://reviews.llvm.org/D144500>), or potentially a custom `apply` reusing some of the interfaces.
