About fifteen years ago, GCC apparently did not seem to support calling

this limitation survived the switch to treessa. Is it true that it's
long gone now?
I don't explicitly recall it going away.
Note that the move to tree-ssa actually makes this kind of thing easier
as the gimplifier will do the evaluation of the argument into a
temporary and use the temporary in the function call.
