Message:

iprt/asm-amd64-x86-watcom-16.h: Another fix for ASMOutStrU8/16/32 - Parameters passed in two (or more) register has fixed order, with BX:SI we'll always get the segment in SI and offset in BX. Switched to DI:SI so we get the segment in DI and offset in SI and don't have to resuffle things.
