Then I hope someone will invest in improving the compilers here. :) I'm not enough of an expert for these low-level parts to judge how much performance they are leaving on the table. But this is simply not something that can be reliably fixed at higher levels of abstraction.
Do you know if there's a bug report against GCC and LLVM discussing the correctness and feasibility of such optimizations?
