Internal compiler error building libstdc++ for vax

[coypu@sdf.org]

(updating)
krister found a better hack patch which explains what the problem is,
adding a useless move at the end of the instruction, so the label is
not the last instruction.

(And, in the problem code, the last instruction in the function.)
