Reviewed by Sam Weinig.
        
Introduced wtf/DataLog, which defines WTF::dataFile, WTF::dataLog,
and WTF::dataLogV. Changed all debugging- and profiling-related printfs
to use WTF::dataLog() or one of its friends. By default, debug logging
goes to stderr, unless you change the setting in wtf/DataLog.cpp.
