Subject: [PATCH] JitArm64: Preserve dirty flag when materializing immediate

Before dbf5dca, the dirty flag had no meaning for an immediate value,
so we made sure to always set the dirty flag when switching a register
from Immediate to Register. But after dbf5dca, that is no longer the
case. If an immediate is marked as not dirty, we can keep the register
marked as not dirty after materializing the value. This way we skip
having to write it back to ppcState later.
