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.

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.

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

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

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

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

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

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.
