Make span6 function (used as LinkArch.Assemble) faster
by avoiding redundant re-assemble rounds on hosts
that are not NaCl.
NaCl is excluded because it needs Prog.Isize to fix alignment.
For make.bash, there are around 50% of functions that can
be encoded in a single trip. With this change, those function
will be assembled with 1 round instead of 2.
