[PATCH] D15057: [PGO] Enable common VP format in profile runtime

Updated the patch according to Betul's feedback.

1. uses getNumValueKindsRT to determine if a function can be skipped (the size method will always return >0 size for the header due to indexed format restriction)
2. enhanced test case to cover the case when no value data is collected -- the resulting profile data should be mergable with the case when value profile data exist

The data race problem to I->Values still exist -- I will have a follow up patch to deal with it.
