Easwaran Raman 1283c1d7af Metadata support for profile summary. 
This adds support to convert ProfileSummary object to Metadata and create a
ProfileSummary object from metadata. This would allow attaching profile summary
information to Module allowing optimization passes to use it.

Easwaran Raman 4bf45e8313 Refactor profile summary support code. NFC. 
Summary computation is not just for instrumented profiling and so I have moved
the ProfileSummary class to ProfileCommon.h (named so to allow code unrelated
to summary but common to instrumented and sampled profiling to be placed there)
