Add O_CREAT to ProfileCompilationInfo::SaveFallback.
Before this change, ProfileCompilationInfo::SaveFallback relies on
ProfileSaver::ProcessProfilingInfo to create an empty file beforehand if
the file didn't exist. This doesn't work if SaveFallback is called by
other callers (e.g., CopyAndUpdateProfileKey), and there can be a race.
After this change, ProcessProfilingInfo no longer creates an empty file,
and SaveFallback creates the file itself.
This change also avoids unnecessary file creation when saving is not
needed.
