libcpp: __VA_OPT__ tweak
> We want to remove the latter <placemarker> but not the former one, and

I notice that the second placemarker you mention is avoid_paste, which seems
relevant. This seems to also work, at least it doesn't seem to break any of
the va_opt tests.

* macro.c (replace_args): When __VA_OPT__ is on the LHS of ##,
remove trailing avoid_paste tokens.
