The reversion apparently deleted the test/Transforms directory.

Will be re-reverting again.

Dehao Chen 38e3731c47 Use call target count to derive the call instruction weight 
Summary: The call target count profile is directly derived from LBR branch->target data. This is more reliable than instruction frequency profiles that could be moved across basic block boundaries. This patches uses call target count profile to annotate call instructions.
