[AArch64][PATCH 7/7] Add NEON intrinsics vqrdmlah_lane and vqrdmlsh_lane.


The ARMv8.1 architecture extension adds two Adv.SIMD instructions,
sqrdmlah and sqrdmlsh. This patch adds the NEON intrinsics vqrdmlah_lane
and vqrdmlsh_lane for these instructions. The new intrinsics are of the
form vqrdml{as}h[q]_lane_<type>.

Tested the series for aarch64-none-linux-gnu with native bootstrap and
make check on an ARMv8 architecture. Also tested aarch64-none-elf with
cross-compiled check-gcc on an ARMv8.1 emulator.

Ok for trunk?
