[PATCH] aarch64: Use type-qualified builtins for vget_low/high intrinsics

Hi,

This patch declares unsigned and polynomial type-qualified builtins for
vget_low_*/vget_high_* Neon intrinsics. Using these builtins removes
the need for many casts in arm_neon.h.

Bootstrapped and regression tested on aarch64-none-linux-gnu - no
issues.

Ok for master?

Thanks,
Jonathan
