[PATCH] aarch64: Reimplement vmovl*/vmovn* intrinsics using __builtin_convertvector

[Kyrylo Tkachov via Gcc-patches]

Hi all,

__builtin_convertvector seems well-suited to implementing the vmovl and vmovn 
intrinsics that widen and narrow
the integer elements in a vector.

This removes some more inline assembly from the intrinsics.
Bootstrapped and tested on aarch64-none-linux-gnu.

Pushing to trunk.
Thanks,
Kyrill
