I'd suggest trying -fmove-loop-invariants, and report a bug about

In general, yes, but we will probably always need some RTL loop
optimizations. Lowering gimple to RTL may expose target dependent loop
invariants that were not present in the gimple. Hence, we still need
the RTL loop pass to work.
Jim you know that -fmove-loop-invariants enables the "new" RTL BB based
loop optimizer? This option was added back in 3.4.0.
