    fold-const: Fix up ((1 << x) & y) != 0 folding for vectors [PR99225]

    This optimization was written purely with scalar integers in mind,
    can work fine even with vectors, but we can't use build_int_cst but
    need to use build_one_cst instead.

            * fold-const.c (fold_binary_loc) <case NE_EXPR>: In (x & (1 << y))
!= 0
            to ((x >> y) & 1) != 0 simplifications use build_one_cst instead of
            build_int_cst (..., 1).  Formatting fixes.
