    aarch64: PR target/95526: Fix gimplification of varargs

    This patch fixes a latent bug exposed by
    eb72dc663e9070b281be83a80f6f838a3a878822 in the aarch64 backend that was
    causing wrong codegen and several testsuite failures. See the discussion
    on the bug for details.

    Bootstrapped and regtested on aarch64-linux-gnu. Cleaned up several
    failing tests and no new fails introduced.
