c7acfdfe9a Add QualifiedDeclRefExpr, which retains additional source-location
information for declarations that were referenced via a qualified-id,
e.g., N::C::value. We keep track of the location of the start of the
nested-name-specifier. Note that the difference between
QualifiedDeclRefExpr and DeclRefExpr does have an effect on the
semantics of function calls in two ways:
  1) The use of a qualified-id instead of an unqualified-id suppresses
     argument-dependent lookup
  2) If the name refers to a virtual function, the qualified-id
  version will call the function determined statically while the
  unqualified-id version will call the function determined dynamically
  (by looking up the appropriate function in the vtable).

Neither of these features is implemented yet, but we do print out
qualified names for QualifiedDeclRefExprs as part of the AST printing.

2eedc3aa1c Add support for member references (E1.E2, E1->E2) with C++ semantics,
which can refer to static data members, enumerators, and member
functions as well as to non-static data members.

Compute the result type of non-static data members of reference type properly.

f3d3faeca6 Rename NamedDecl::getName() to getNameAsString(). Replace a bunch of
uses of getName() with uses of getDeclName().  This upgrades a bunch of
diags to take DeclNames instead of std::strings.

This also tweaks a couple of diagnostics to be cleaner and changes
CheckInitializerTypes/PerformInitializationByConstructor to pass
around DeclarationNames instead of std::strings.

9b1335eca8 Fix redundant load of bit-fields on assignment (to get the updated

   write update bit-field value if caller requires it.

993603d80d Add a new expression node, CXXOperatorCallExpr, which expresses a
function call created in response to the use of operator syntax that
resolves to an overloaded operator in C++, e.g., "str1 +
str2" that resolves to std::operator+(str1, str2)". We now build a
CXXOperatorCallExpr in C++ when we pick an overloaded operator. (But
only for binary operators, where we actually implement overloading)

I decided *not* to refactor the current CallExpr to make it abstract
(with FunctionCallExpr and CXXOperatorCallExpr as derived
classes). Doing so would allow us to make CXXOperatorCallExpr a little
bit smaller, at the cost of making the argument and callee accessors
virtual. We won't know if this is going to be a win until we can parse
lots of C++ code to determine how much memory we'll save by making
this change vs. the performance penalty due to the extra virtual
calls.

1c64e5d12f Refactor some CodeGen functionality:
- Add CodeGenFunction::{EmitReturnOfRValue, EmitIvarOffset}
 - Factor EmitLValueForIvar out of EmitObjCIvarRefLValue.

No non-error functionality change (some unsupported errors are
degraded to asserts for the time being).

41cf9dedc6 Change CodeGen to emit calls using (RValue,Type) list:
- Add CodeGenFunction::EmitAnyExprToTemp
   o Like EmitAnyExpr, but emits aggregates to a temporary location if
     none is available. Seems like this should be simpler (even aside
     from using first class aggregates).

 - Killed CodeGenFunction::EmitCallArg (just append the pair)

 - Conversion of RValues to actual call arguments is now isolated in
   CodeGenFunction::EmitCall.

4b8c6db927 Add Objective-C property setter support.
- Change Obj-C runtime message API, drop the ObjCMessageExpr arg in
   favor of just result type and selector. Necessary so it can be
   reused in situations where we don't want to cons up an
   ObjCMessageExpr.
 - Update aggregate binary assignment to know about special property
   ref lvalues.
 - Add CodeGenFunction::EmitCallArg overload which takes an already
   emitted rvalue.

Add CodeGenFunction::StoreComplexIntoAddr.

Disabled logic in Sema for parsing Objective-C dot-syntax that
accesses methods. This code does not search in the correct order and
the AST node has no way of properly representing its results.

Updated StmtDumper to print a bit more information about
ObjCPropertyRefExprs.

c722b8565c Refactor handling of calls:
- Added CodeGenFunction::EmitCall which just takes the callee, return
   type, and a list of (Value*,QualType) pairs.
 - Added CodeGenFunction::EmitCallArg which handles emitting code for
   a call argument and turning it into an appropriate
   (Value*,QualType) pair.
 - Changed Objective-C runtime interface so that the actual emission
   of arguments for message sends is (once again) done in the code to
   emit a message send.

No intended functionality change, this is prep work for better ABI
support and for Objective-C property setter support.

f2e69888c5 Support __PRETTY_FUNCTION__ and friends in Obj-C methods.
Add CodeGenFunction::EmitUnsupportedLValue 
 - Gives error and returns undef value.

Swap some asserts() over to using EmitUnsupportedLValue
 - Rumor has it users (and even some developers) prefer carat
   diagnostics to backtraces.
 - Works better in Release-Asserts to boot.
