    ifcvt: Reject inner floating modes of a subreg for noce_try_cond_zero_arith
[PR123491]

    Like the check that was added in
r16-6374-g2680785a6d14d7d78550edb8361f3b47eb5c4cb6,
    except this is for the new code that was added with
r16-6436-g92f2a86794ad88d773b102.
    Basically the code only expects to work with scalar integer modes but
forgot
    to check that.

    Pushed as obvious after bootstrap/test on x86_64-linux-gnu.

            PR rtl-optimization/123491
    gcc/ChangeLog:

            * ifcvt.cc (noce_try_cond_zero_arith): Reject non-scalar
            integer modes for the inner mode of the subreg.
