a74948d347 Correctly parse braced member initializers (even in delayed parsing) and correctly pass
the information on to Sema. There's still an incorrectness in the way template instantiation
works now, but that is due to a far larger underlying representational problem.
Also add a test case for various list initialization cases of scalars, which test this
commit as well as the previous one.

5cec2aea3f Support code-completion for C++ inline methods and ObjC buffering methods.
Previously we would cut off the source file buffer at the code-completion
point; this impeded code-completion inside C++ inline methods and,
recently, with buffering ObjC methods.

Have the code-completion inserted into the source buffer so that it can
be buffered along with a method body. When we actually hit the code-completion
point the cut-off lexing or parsing.

7b8c3c91f4 PR10359: Template declarations which define classes are not permitted to also contain declarators. Previously we would accept code like this:
template<typename T> struct S { } f() { return 0; }

This case now produces a missing ';' diagnostic, since that seems like a much more likely error than an attempt to declare a function or variable in addition to the class template.

cd1c055528 Fix AST representations of alias-declarations which define tag types. Inside classes, the tag types need to have an associated access specifier, and inside function definitions, they need to be included in the declarations of the DeclStmt.

c15b0cfc1f When deciding how to parse "= something" as part of a member
declaration, determine whether the declaration will end up declaring a
function using semantic criteria (e.g., it will have function type)
rather than purely syntactic criteria (e.g., it has the form of a
function declarator). Fixes <rdar://problem/9670557>.

4a4beec7b0 Don't assert on initialized typedef declarations in classes:
struct {
    typedef int A = 0;
  };

According to the C++11 standard, this is not ill-formed, but does not have any ascribed meaning. We can't reasonably accept it, so treat it as ill-formed.

Also switch C++ from an incorrect 'fields can only be initialized in constructors' diagnostic for this case to C's 'illegal initializer (only variables can be initialized)'

5a7fa250ab Properly parse the 'default' and 'delete' keywords.
They are actually grammatically considered definitions and parsed
accordingly.

This fixes the outstanding bugs regarding defaulting functions after
their declarations.

We now really nicely diagnose the following construct (try it!)

int foo() = delete, bar;

Still todo: Defaulted functions other than default constructors

7c9856deb3 When parsing a template friend declaration we dropped the template
parameters on the floor in certain cases:
class X {
  template <typename T> friend typename A<T>::Foo;
};

This was parsed as a *non* template friend declaration some how, and
received an ExtWarn. Fixing the parser to actually provide the template
parameters to the freestanding declaration parse triggers the code which
specifically looks for such constructs and hard errors on them.

Along the way, this prevents us from trying to instantiate constructs
like the above inside of a outer template. This is important as loosing
the template parameters means we don't have a well formed declaration
and template instantiation will be unable to rebuild the AST. That fixes
a crash in the GCC test suite.
