4aa04b155a Slight improvement for extern templates, so that an explicit
instantiation definition can follow an explicit instantiation
declaration. This is as far as I want to go with extern templates now,
but they will still need quite a bit more work to get all of the C++0x
semantics right.

308047d3a5 Initial stab at implement dependent member references to member
templates, e.g.,
  
  x.template get<T>

We can now parse these, represent them within an UnresolvedMemberExpr
expression, then instantiate that expression node in simple cases.

This allows us to stumble through parsing LLVM's Casting.h.

ad8a336b40 Implement AST, semantics, and CodeGen for C++ pseudo-destructor
expressions, e.g.,

  p->~T()

when p is a pointer to a scalar type. 

We don't currently diagnose errors when pseudo-destructor expressions
are used in any way other than by forming a call.

2b6ca46c6b Improve template instantiation for member access expressions that
involve qualified names, e.g., x->Base::f. We now maintain enough
information in the AST to compare the results of the name lookup of
"Base" in the scope of the postfix-expression (determined at template
definition time) and in the type of the object expression.

c26e0f626b Improved handling for dependent, qualified member access expressions, e.g.,
t->Base::f

where t has a dependent type. We save the nested-name-specifier in the
CXXUnresolvedMemberExpr then, during instantiation, substitute into
the nested-name-specifier with the (transformed) object type of t, so
that we get name lookup into the type of the object expression.

Note that we do not yet retain information about name lookup into the
lexical scope of the member access expression, so several regression
tests are still disabled.

f15d4b6050 This patch does the following.
1) Issue digsnostics in non-fragile ABI, when an expression
   evaluates to an interface type (except when it is used to
   access a non-fragile ivar).
2) Issue unsupported error in fragile ABI when an expression
   evaluates to an interface type (except when it is used to
   access a fragile ivar).

f405d7e6f1 Eliminate CXXAdornedMemberExpr entirely. Instead, optionally allocate
space within the MemberExpr for the nested-name-specifier and its

896c230a19 Improve diagnostics for missing members. This renames the err_typecheck_no_member to err_typecheck_no_member_deprecated. The idea is that err_typecheck_no_member_deprecated should be phased out and any call sites that reference it should call DiagnoseMissingMember instead.

01afeeff1d Implement template instantiation for member class templates.
When performing template instantiation of the definitions of member
templates (or members thereof),  we build a data structure containing
the template arguments from each "level" of template
instantiation. During template instantiation, we substitute all levels
of template arguments simultaneously.

c190523d7a When a member reference expression includes a qualifier on the member
name, e.g.,
  
  x->Base::f()

retain the qualifier (and its source range information) in a new
subclass of MemberExpr called CXXQualifiedMemberExpr. Provide
construction, transformation, profiling, printing, etc., for this new
expression type.

When a virtual function is called via a qualified name, don't emit a
virtual call. Instead, call that function directly. Mike, could you
add a CodeGen test for this, too?

f8344dbfdd tweak some pointer sema checking stuff (which was added to implement PR4175) to
avoid emitting a warning on "someptr > 0".  This is obviously questionable (they 
could use != instead) but is reasonable, and the warning "ordered comparison 
between pointer and integer" didn't make a ton of sense because 0 is a valid 
null pointer constant.

Just silence the warning in this case, it is unlikely to indicate a bug.

- Allowing one to name a member function template within a class
  template and on the right-hand side of a member access expression.
  - Template argument deduction for calls to member function templates.
  - Registering specializations of member function templates (and
  finding them later).
