01fe58047e Try to solve the Bitu formatting warning on all supported platforms (both 32 and 64 bit). Did a few places. Still a lot to go. Changed default display of Bitu to be unsigned instead of signed.

41126f8ff9 Fix unused-function warning 
This function is used only inside x86 ifdef, so move it to prevent the
warning. Also, use this opportunity to improve readability a bit.

4a01b6a00d Prevent potential null pointer dereference 
This null-check resolves a potential issue detected by static analysis.

It might be the case, that crash never happens due to the way this
static function is used at the moment, and because DYNFLG_CHANGED is being
cleared in dnew->genreg->Clear() few lines before, but the crash might
still happen if initial state of flags is inconsistent or surrounding
code will be changed even a little bit.

This nullcheck makes the code more robust at no performance penalty.
