[PATCH] D66513: [SampleFDO] Add ExtBinary format to support extension of binary profile

[Wei Mi via Phabricator via llvm-commits]

wmi updated this revision to Diff 216677.
wmi added a comment.

Address David's comment.
Add ExtBinaryBase class for the basics of extensible format and ExtBinary inherits from it, so we can add other types of profiles in extensible format separately.  
Some refactoring and comment changes.
