BTW, the reason I moved these functions from tree-complex.c is that they 
may be useful elsewhere (Roger once talked me about using something like 
these to produce GIMPLE in the builtin function folders).

I renamed them because do_unop/do_binop is not a nice name for a public 
function.  Also, the vector patch adds back the names do_unop and 
do_binop in tree-complex.c for a different thing (they are callbacks to 
lower a vector unary and binary operation respectively; I like naming 
callbacks do_something).
