[PATCH] D11241: Create a wrapper pass for BranchProbabilityInfo so that branch probability analysis can be done without requiring a pass.

This patch is similar to the one adding a wrapper to BlockFrequencyInfo. The patch creates a wrapper pass for BranchProbabilityInfo. This is useful when we want to do branch probability analysis conditionally (e.g. only in PGO mode) but don't want to add one more pass dependence.
