Fariborz Jahanian 681c0754d9 Eliminate usage of ObjCSuperExpr used for 
'super' as receiver of property or a setter/getter
methods. //rdar: //8525788

Douglas Gregor e572b068ab Fix classification of statement expressions.

Fariborz Jahanian 805b74ea30 RHS of property expression assignment requires 
copy initialization before passing it to 
a setter. Fixes radar 8427922.

Douglas Gregor 4e4425030a Eliminate the default case in the expression-classification code, so 
that we're sure to keep it updated when new expression kinds
emerge. Also fixes a few little bugs in the classification of
expressions.

Fariborz Jahanian e89d03f619 property reference expression used on lhs of assignment 
follows objective's semantics and is not overload'able
with an assignment operator. Fixes a crash and a missing
diagnostics. Radar 8379892.

John McCall 8d08b9b408 Propagate whether an id-expression is the immediate argument of 
an '&' expression from the second caller of ActOnIdExpression.

Teach template argument deduction that an overloaded id-expression
doesn't give a valid type for deduction purposes to a non-static
member function unless the expression has the correct syntactic
form.

Teach ActOnIdExpression that it shouldn't try to create implicit
member expressions for '&function', because this isn't a        
permitted form of use for member functions.

Teach CheckAddressOfOperand to diagnose these more carefully.
Some of these cases aren't reachable right now because earlier
diagnostics interrupt them.

John McCall e302792b61 GCC didn't care for my attempt at API compatibility, so brute-force everything 
to the new constants.

John McCall 2536c6da0e More incremental progress towards not including Expr.h in Sema.h.

Douglas Gregor 747eb7840a Reinstate the fix for PR7556. A silly use of isTrivial() was 
suppressing copies of objects with trivial copy constructors.

Douglas Gregor e182370eda Revert r107828 and r107827, the fix for PR7556, which seems to be 
breaking bootstrap on Linux.

Douglas Gregor 6df2b8c3ac Rename CXXZeroInitValueExpr to CXXScalarValueInitExpr, to reflect its 
newly-narrowed scope. No functionality change.

Chandler Carruth 8337ba6303 Prefer llvm_unreachable(...) to assert(false && ...). This is important as 
without it we might exit a non-void function without returning.

Sebastian Redl f9463106b3 Introduce Expr::Classify and Expr::ClassifyModifiable, which determine the classification of an expression under the C++0x taxology (value category). Reimplement isLvalue and isModifiableLvalue using these functions. No regressions in the test suite from this, and my rough performance check doesn't show any regressions either.
