  [AArch64] Make target intrinsics DefaultAttrIntrinsics.

DefaultAttrIntrinsics was introduced to add very common attributes to a
large set of intrinsics.

Currently the added attributes include:

    nofree nosync nounwind willreturn

I think those should hold for most AArch64 target intrinsics, but
there are too many to check manually. This patch makes most AArch64 target
intrinsics DefaultAttrsIntrinsics.

Some notable exceptions I think are exclusive loads and stores as well
as the memory barrier intrinsics, for which nosync does not apply I
think.
