Douglas Gregor 24c332b140 Link FunctionDecls instantiated from the member functions of a class
template to the FunctionDecls from which they were instantiated. This
is a necessary first step to support instantiation of the definitions
of such functions, but by itself does essentially nothing.

Daniel Dunbar 0a2171ccd5 Skip the asm prefix when storing the name in block info.
- Otherwise we emit internal names with embedded '\01' characters,
   which confuses some tools.

 - Ideally all the code which wants to get a "display name" for the
   given function should follow one code path, but this should be a
   monotonic improvement for now.

Douglas Gregor d9034f0b89 In C++, warn when something previously declared as a "struct" is later
declared as a "class", or vice-versa. This warning is under the
control of -Wmismatched-tags, which is off by default.

Daniel Dunbar 7911002bf9 We need to specify the "linkage name" to the subprogram now that we
emit the correct "display name". I suspect we need more work here, see
FIXME for example.

Douglas Gregor 2ec748cd5a Implement explicit instantiations of member classes of class templates, e.g.,
template<typename T>
  struct X {
    struct Inner;
  };

  template struct X<int>::Inner;

This change is larger than it looks because it also fixes some
a problem with nested-name-specifiers and tags. We weren't requiring
the DeclContext associated with the scope specifier of a tag to be
complete. Therefore, when looking for something like "struct
X<int>::Inner", we weren't instantiating X<int>. 

This, naturally, uncovered a problem with member pointers, where we
were requiring the left-hand side of a member pointer access
expression (e.g., x->*) to be a complete type. However, this is wrong:
the semantics of this expression does not require a complete type (EDG
agrees).

Stuart vouched for me. Blame him.

Daniel Dunbar 0aef72c697 Add a test case to showcase a difference in #pragma pack handling

"correct" thing, and if I recall correctly I previously verified this
versus MSVC.

Ted Kremenek 3b204e4c2e Add some basic type checking for attributes ns_returns_retained and
cf_returns_retained. Currently this attribute can now be applied to any
Objective-C method or C function that returns a pointer or Objective-C object
type.

Modify the tablegen definition of diagnostic 'warn_attribute_wrong_decl_type' to
expect that the diagnostics infrastructure will add quotes around the attribute
name when appropriate. Alonq with this change, I modified the places where this
warning is issued to passed the attribute's IdentifierInfo* instead of having a
hard-coded C constant string.

Daniel Dunbar ffdb8439d7 ABI handling: Fix invalid assertion, it is possible for a valid
coercion to be specified which truncates padding bits. It would be
nice to still have the assert, but we don't have any API call for the
unpadding size of a type yet.

Douglas Gregor f61eca93c0 Improve the semantic checking for explicit instantiations of
templates. In particular:
  - An explicit instantiation can follow an implicit instantiation (we
  were improperly diagnosing this as an error, previously).
  - In C++0x, an explicit instantiation that follows an explicit
  specialization of the same template specialization is ignored. In
  C++98, we just emit an extension warning.
  - In C++0x, an explicit instantiation must be in a namespace
  enclosing the original template. C++98 has no such requirement.

Also, fixed a longstanding FIXME regarding the integral type that is
used for the size of a constant array type when it is being instantiated.

Chris Lattner 851eb927d7 Fix rdar://6881069, a crash on a form of vector_size that we
don't support.  While it would be nice to support this eventually,
this form is not common at all (just seen in gcc testsuite) and
it might be better to model vector_size as a type attribute anyway.
For now just emit a nice error on it.

Douglas Gregor 2399628cea Refactor the parsing of declarations so that template declarations can

require thatn the layout of a DeclGroup of a single element be the
same as the layout of a single declaration.
