What do you think it is possible to use built in profiler of firefox or 
chrome to record call statistics and then use output json file as alternate 
parameter for DEAD_FUNCTIONS.
For example I get CPU-20161028T023927.cpuprofile from Google Chrome and 
then use it as -s DEAD_FUNCTIONS_EXCLUDE=CPU-20161028T023927.cpuprofile

Is it useful? or I can just write extractor from profiler results and 
generate intersections with all functions from emscripten output, and then 
use this intersection in DEAD_FUNCTIONS
