And other minor leak. This time in tree-stdarg. Unlike other cases,
we're dropping just the virtual definition, other definitions on the
statement need to be preserved (they're going to be re-used).
Additionally, this one is missing the call to unlink_stmt_vdef.
Like other cases, I've got a minimized test, but no good way to add it
to the testsuite right now.
Bootstrapped and regression tested on x86_64-linux-gnu. Installed on
the trunk.
