function correctly when targeting MS ABIs (this appears to have never mattered prior to this change). Update test case to always cover both 32-bit and 64-bit Windows ABIs, since they behave somewhat differently from each other here. Update test case to also cover operators , && and ||, which it appears are also affected by P0145R3 (they're not explicitly called out by the design document, but this is the emergent behavior of the existing wording). Original commit message: P0145R3 (C++17 evaluation order tweaks): evaluate the right-hand side of assignment and compound-assignment operators before the left-hand side. (Even if it's an overloaded operator.) This completes the implementation of P0145R3 + P0400R0 for all targets except Windows, where the evaluation order guarantees for <<, >>, and ->* are unimplementable as the ABI requires the function arguments are evaluated from right to left (because parameter destructors are run from left to right in the callee). llvm-svn: 282619
