Implement name lookup for conversion function template specializations
(C++ [temp.mem]p5-6), which involves template argument deduction based
on the type named, e.g., given
struct X { template<typename T> operator T*(); } x;
when we call
x.operator int*();
we perform template argument deduction to determine that T=int. This
template argument deduction is needed for template specialization and
explicit instantiation, e.g.,
template<> X::operator float*() { /* ... */ }
and when calling or otherwise naming a conversion function (as in the
first example).
This fixes PR5742 and PR5762, although there's some remaining ugliness
that's causing out-of-line definitions of conversion function
templates to fail. I'll look into that separately.
