Move cabs expansion from powcabs to complex lowering [PR115710]
Expanding cabs in powcab might be too late as forwprop might
recombine the load from a memory with the complex expr. Moving
instead to complex lowering allows us to use directly the real/imag
component from the loads instead. This allows for vectorization too.
Bootstrapped and tested on x86_64-linux-gnu with no regressions.
