Thanks for the update. The new patch looks really good, just some
minor comments.

Hi all,
This patch adds Bfloat type support to the ARM back-end.
It also adds a new machine_mode (BFmode) for this type and accompanying Vector
modes V4BFmode and V8BFmode.
The second patch in this series uses existing target hooks to restrict type use.
