-Wuninitialized: don't issue fixit for initializer if a variable declaration already has an initializer.

When emitting a "too many arguments to function call..." error, also include a note with a location for the function prototype.

I'm pretty sure this is the right fix, but I would appreciate it if someone
else would double-check.

location into a TemplateSpecializationTypeLoc. These were found using
a hand-written program to inspect every source location in
TemplateSpecializationTypeLocs and Valgrind. I don't know of any way to
test them in Clang's existing test suite sadly.

Example code that triggers the ElaboratedType case:
  template <typename T> struct X1 {
    template <typename U> struct X1_1 {
      int x;
    };
  };

  template <typename T, typename U> struct X2 {
    typename X1<T>::template X1_1<U> B;
  };

  X2<char, int> x2;

The other fix was simply spotted by inspection. I audited all constructions of
[Dependent]TemplateSpecializationTypeLocs in TreeTransform.h, and the rest set
the TemplateNameLoc properly.

when the resolution took place due to a single template specialization
being named with an explicit template argument list. In this case, the
"resolution" doesn't take into account the target type at all, and
therefore can take place for functions, static member functions, and
*non-static* member functions. The latter weren't being properly checked
and their proper form enforced in this scenario. We now do so.

The result of this last form slipping through was some confusing logic
in IsStandardConversion handling of these resolved address-of
expressions which eventually exploded in an assert. Simplify this logic
a bit and add some more aggressive asserts to catch improperly formed
expressions getting into this routine.

Finally add systematic testing of member functions, both static and
non-static, in the various forms they can take. One of these is
essentially PR9563, and this commit fixes the crash in that PR. However,
the diagnostics for this are still pretty terrible. We at least are now
accepting the correct constructs and rejecting the invalid ones rather
than accepting invalid or crashing as before.

This is basically the same idea as the warning on uninitialized uses of
fields within an initializer list. As such, it is on by default and
under -Wuninitialized.

Original patch by Richard Trieu, with some massaging from me on the
wording and grouping of the diagnostics.

lookup of explicit visibility so that we search for both an explicit
VisibilityAttr and an appropriate AvailabilityAttr, favoring the
VisibilityAttr if it is present.
