QtStartUpFunction is written as QtCleanUpFunction

I'm not entirely sure if this is actually a typo or not, but let me point it out just to make sure it's not getting missed.

In the file qcoreapplication.cpp, there's a function called qt_call_pre_routines(), which basically calls a list of QtStartUpFunctions, as the name suggests.
It takes a list of QtStartUpFunctions from preRList and loops through it with for loop. 
However, it's taking each element as a type of QtCleanUpFunction, not QtStartUpFunction.
If this is actually written as intended, perhaps adding a comment to the code would help for understanding.
