    AArch64: Implement Armv8.3-a complex arithmetic intrinsics

    I'd like to backport some patches from Tamar in GCC 9 to GCC 8 that
implement the complex arithmetic intrinsics for Advanced SIMD.
    These should have been present in GCC 8 that gained support for Armv8.3-a.

    There were 4 follow-up fixes that I've rolled into the one commit.

    Bootstrapped and tested on aarch64-none-linux-gnu and
arm-none-linux-gnueabihf on the GCC 8 branch.
