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
source range. We'll do the same thing with explicitly-specified
template arguments, assuming I don't flip-flop again.

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?

d99bd52c73 Eli points out that we really must diagnose "void* > 0" as an extension.
Explicitly add it as an EXTENSION instead of an EXTWARN so that it only
comes out with -pedantic.  Thanks Eli!

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.

97628d6a4c Implement support for calling member function templates, which involves:
- 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).

9f57c29053 Initial patch to support definitions of id and Class from headers in Objective-C code.
This currently breaks test/SemaObjC/id-isa-ref.m and issues some spurious warnings when you attempt to assign a struct objc_class* value to a Class variable.  The test case probably should fail as it's written, because without the definition of Class the compiler should not assume struct objc_class* is a valid receiver type, but it's left broken because it would be nice if we could get that passing too for the special case of isa.

Approved by snaroff.

Addresses Eli's patch feedback re: ugly cast code

Updates all postfix operators to remove ParenListExprs.  While this is awful,
no better solution (say, in the parser) is obvious to me.  Better solutions
welcome.
