Rework parsing of pseudo-destructor expressions and explicit
destructor calls, e.g.,
p->T::~T
We now detect when the member access that we've parsed, e.g.,
p-> or x.
may be a pseudo-destructor expression, either because the type of p or
x is a scalar or because it is dependent (and, therefore, may become a
scalar at template instantiation time).
We then parse the pseudo-destructor grammar specifically:
::[opt] nested-name-specifier[opt] type-name :: ∼ type-name
and hand those results to a new action, ActOnPseudoDestructorExpr,
which will cope with both dependent member accesses of destructors and
with pseudo-destructor expressions.
This commit affects the parsing of pseudo-destructors, only; the
semantic actions still go through the semantic actions for member
access expressions. That will change soon.
