Make sure isCopyAssignment is only true for actual copy assignment operators, instead of all assignment operators. The mistake messes up IRGen because it ends up assuming that the assignment operator is actually the implicit copy assignment operator, and therefore tries to emit the RHS as an lvalue. llvm-svn: 86307

Turn access control on by default in -cc1. Remove -faccess-control from -cc1; add -fno-access-control. Make the driver pass -fno-access-control by default. Update a bunch of tests to be correct under access control. llvm-svn: 100880
