I think this still needs a backport to GCC 5 though

Thanks for the reminder. I will commit the back-port today. I wanted leave few
days in the trunk before doing.

--- Comment #1 from ktkachov at gcc dot gnu.org ---
Confirmed on trunk and 5 branch.
4.9 doesn't build for language-level issues (different intrinsics
implementation back then or something)
-O2 -std=gnu++11 -mfpu=neon -S  -w -mfloat-abi=softfp
is needed. -mfloat-abi=hard doesn't ICE
