Existing code tended to assume that counters had type `uint64_t` and computed size from the number of counters. Fix this code to directly compute the counters size in number of bytes where possible. When the number of counters is needed, use `__llvm_profile_counter_entry_size()` or `getCounterTypeSize()`. In a later diff these functions will depend on the profile mode. Change the meaning of `DataSize` and `CountersSize` to make them more clear. * `DataSize` (`CountersSize`) - the size of the data (counter) section in bytes. * `NumData` (`NumCounters`) - the number of data (counter) entries.
