Don't put operands in clobber lists, since this is dubious for old
versions of gcc and broken for current versions of egcs. The asm
here (for translate_bytes()) is now an interesting example of one
that needs to be volatile to work.
Fixed missing "memory" in the clobber list for translate_bytes().
Submitted by: "John S. Dyson" <dyson@iquest.net> but rewritten by me
