x86-64: make pda's cpunumber and nodenumber unsigned
This generally allows better code to be generated, since the zero- extension during 32-bit operations comes for free (needed when the result is used as array index or similar), whereas sign extension must be done explicitly and frequently requires a one byte larger instruction due to the necessary rex64 prefix.
