Although we currently have explicit lvalue-to-rvalue conversions, they're not actually frequently used, because ImpCastExprToType only creates a node if the types differ. So explicitly create an ICE in the lvalue-to-rvalue conversion code in DefaultFunctionArrayLvalueConversion() as well as several other new places, and consistently deal with the consequences throughout the compiler. In addition, introduce a new cast kind for loading an ObjCProperty l-value, and make sure we emit those nodes whenever an ObjCProperty l-value appears that's not on the LHS of an assignment operator. This breaks a couple of rewriter tests, which I've x-failed until future development occurs on the rewriter. Ted Kremenek kindly contributed the analyzer workarounds in this patch. llvm-svn: 120890 2010-12-04 11:47:34 +08:00			`// RUN: %clang_cc1 -ast-dump %s 2>&1 \| grep ImplicitCastExpr \| count 4`
