    aarch64: PR target/108140 Handle NULL target in data intrinsic expansion

    In this PR we ICE when expanding the __rbit builtin with a NULL target =
rtx.
    I *think* that only happens when the result is unused and hence maybe we
shouldn't be expanding
    any RTL at all, but the ICE here is easily fixed by deriving the mode f=
rom
the type of the expression
    rather than the target.

    This patch does that.
    Bootstrapped and tested on aarch64-none-linux-gnu.
