I'm working on this bug among other improvements to RTL hoist pass.
My plan is to enable hoisting of such simple constants, but only on very short
distances, like 3-5 instructions, tunable through a new parameter. Targets
like x86 can disable simple constant hoisting altogether, while targets like
ARM would be able to enable it when optimizing for size.
