This change refactors the ProfileKind enum into a bitset enum to
represent the different attributes a profile can have. This change
simplifies the logic in the instrprof writer when multiple profiles are
merged together. In the future we plan on introducing a new memory
profile section which will extend the enum by one additional entry.
Without this change when accounting for memory profiles will have to be
maintained separately and will make the logic more complex.
