Reimplement constructor declarator parsing to cope with template-ids
that name constructors, the endless joys of out-of-line constructor
definitions, and various other corner cases that the previous hack
never imagined. Fixes PR5688 and tightens up semantic analysis for
constructor names.
Additionally, fixed a problem where we wouldn't properly enter the
declarator scope of a parenthesized declarator. We were entering the
scope, then leaving it when we saw the ")"; now, we re-enter the
declarator scope before parsing the parameter list.
Note that we are forced to perform some tentative parsing within a
class (call it C) to tell the difference between
C(int); // constructor
and
C (f)(int); // member function
which is rather unfortunate. And, although it isn't necessary for
correctness, we use the same tentative-parsing mechanism for
out-of-line constructors to improve diagnostics in icky cases like:
C::C C::f(int); // error: C::C refers to the constructor name, but
// we complain nicely and recover by treating it as
// a type.
