    [COMMITTED] Fix PR aarch64/104474: ICE with vector float initializers and
non-consts.

    The problem here is that the aarch64 back-end was placing const0_rtx
    into the constant vector RTL even if the mode was a floating point mode.
    The fix is instead to use CONST0_RTX and pass the mode to select the
    correct zero (either const_int or const_double).

    Committed as obvious after a bootstrap/test on aarch64-linux-gnu with
    no regressions.
