ARM v8.1a adds Advanced SIMD instructions for Rounding Double Multiply
Add/Subtract.

The following instructions are added to AArch32 instruction set:

- VQRDMLAH: Vector Saturating Rounding Doubling Multiply Accumulate
            Returning High Half
- VQRDMLSH: Vector Saturating Rounding Doubling Multiply Subtract
            Returning High Half

The following instructions are added to AArch64 instruction set:

- SQRDMLAH: Signed Saturating Rounding Doubling Multiply Accumulate
            Returning High Half
- SQRDMLSH: Signed Saturating Rounding Doubling Multiply Subtract
            Returning High Half

This patch adds intrinsic and ACLE macro support for these instructions,
as well as corresponding tests.
