Okay, so this is wrong in every way. :)
Expression mangling generally follows the syntax. Since there is no
argument-side syntax for passing an argument to an `out` or `inout` parameter,
I'd say the correct mangling is just to ignore this node and mangle the
underlying (syntactic) argument expression, which I assume is fairly easy to
find (is that the base expression? whatever doesn't have the OVE still in it).
If it *were* important to mangle this for some reason, you would want to mangle
it as a vendor extended expression, `u <source-name> <template-arg>* E`.
