Gui: Always declare qt_memfill{32|64} as function pointers on x86
Having the declaration of a function depend on compiler flags is a
fundamentally bad idea since you can compile different compilation units
that all include the header with different flags. This leads to
undefined symbols.
Pick-to: 6.5
