John McCall ec8045d3f0 Implicit decl ref expressions might not have name locations; don't silently
fail to instantiate them.

Douglas Gregor 1eabb7d0c3 Improve diagnostics when an elaborated-type-specifer containing a
nested-name-specifier (e.g., "class T::foo") fails to find a tag
member in the scope nominated by the
nested-name-specifier. Previously, we gave a bland

  error: 'Nested' does not name a tag member in the specified scope

which didn't actually say where we were looking, which was rather
horrible when the nested-name-specifier was instantiated. Now, we give
something a bit better:

  error: no class named 'Nested' in 'NoDepBase<T>'

Daniel Dunbar a5728872c7 Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

Douglas Gregor c86a6e9881 When performing template instantiation (transformation) of
expressions, keep track of whether we are immediately taking the
address of the expression. Pass this flag when building a declaration
name expression so that we handle pointer-to-member constants
properly.

Douglas Gregor 7b0a5723d6 Follow-on test case for template instantiation of interesting DeclGroups

Douglas Gregor 8e92bf33ba Now that we have declared/defined tag types within DeclGroups,
instantiation of tags local to member functions of class templates
(and, eventually, function templates) works when the tag is defined as
part of the decl-specifier-seq, e.g.,

  struct S { T x, y; } s1;

Also, make sure that we don't try to default-initialize a dependent
type.

Douglas Gregor bc221637f5 Introduced DeclContext::isDependentContext, which determines whether a
given DeclContext is dependent on type parameters. Use this to
properly determine whether a TagDecl is dependent; previously, we were
missing the case where the TagDecl is a local class of a member
function of a class template (phew!).

Also, make sure that, when we instantiate declarations within a member
function of a class template (or a function template, eventually),
that we add those declarations to the "instantiated locals" map so
that they can be found when instantiating declaration references.

Unfortunately, I was not able to write a useful test for this change,
although the assert() that fires when uncommenting the FIXME'd line in
test/SemaTemplate/instantiate-declref.cpp tells the "experienced user"
that we're now doing the right thing.

Douglas Gregor 6569d68745 Reimplement much of the way that we track nested classes in the
parser. Rather than placing all of the delayed member function
declarations and inline definitions into a single bucket corresponding
to the top-level class, we instead mirror the nesting structure of the
nested classes and place the delayed member functions into their
appropriate place. Then, when we actually parse the delayed member
function declarations, set up the scope stack the same way as it was
when we originally saw the declaration, so that we can find, e.g.,
template parameters that are in scope.

Douglas Gregor ed961e7fff Simplify, and improve the performance of, template instantiation for
declaration references. The key realization is that dependent Decls,
which actually require instantiation, can only refer to the current
instantiation or members thereof. And, since the current context
during instantiation contains all of those members of the current
instantiation, we can simply find the real instantiate that matches up
with the "current instantiation" template.

Douglas Gregor d0c8737996 Add some more tests for instantiation of declaration references. Also,
improve some error recovery with explicit template instantiation.

Douglas Gregor 8dbc3c6496 Enumeration declarations that were instantiated from an enumeration
within a template now have a link back to the enumeration from which
they were instantiated. This means that we can now find the
instantiation of an anonymous enumeration.

Douglas Gregor 2bba76b0ec Improve name lookup for and template instantiation of declaration
references. There are several smallish fixes here:

  - Make sure we look through template parameter scope when
    determining whether we're parsing a nested class (or nested class
    *template*). This makes sure that we delay parsing the bodies of
    inline member functions until after we're out of the outermost
    class (template) scope.
  - Since the bodies of member functions are always parsed
    "out-of-line", even when they were declared in-line, teach
    unqualified name lookup to look into the (semantic) parents.
  - Use the new InstantiateDeclRef to handle the instantiation of a
    reference to a declaration (in DeclRefExpr), which drastically
    simplifies template instantiation for DeclRefExprs.
  - When we're instantiating a ParmVarDecl, it must be in the current
    instantiation scope, so only look there.

Also, remove the #if 0's and FIXME's from the dynarray example, which
now compiles and executes thanks to Anders and Eli.
