My thought was that we could use alignment alone if we didn't know the sizes of
instructions on targets like i386 with variable instruction lengths, as a
guesstimate, to do better than chance.  On RISC targets with fixed instruction
length like SPARC it should be possible to get the size just by counting
instructions.  I don't know this part of GCC so I have no idea what's
available.
