This problem appears to affect the ARM port as well - I can see this
being useful for the ARM port and might force us to look at
TARGET_ADDRESS_COST a little more carefully - so if you're happy to post
the fwprop patch I'm happy to test for performance on the ARM and look
at ADDRESS_COST carefully on the ARM.
