I've had this in my tree for a few months now but never got
around to submitting it.

This partially fixes PR target/53440 atleast in ARM and
Thumb2 state. I haven't yet managed to get my head around
rewriting the Thumb1 support yet.

Tested on armhf with a bootstrap and regression test
with no regressions.

Queued for stage1 now as it isn't technically a regression.

regards
Ramana
