If you write them with nomacro in effect, you can...  Doesn't gcc use
the rule that the length of an asm is the length attribute defined in
the md file, multiplied by the number of statements in the asm string?
Actually, even with macros that works if the md file specifies the
longest macro expansion as its length, but that's rather pessimistic.
