[RTL-ifcvt] PR rtl-optimization/67465: Handle pairs of complex+simple blocks and empty blocks more gracefully

        PR rtl-optimization/67456
        PR rtl-optimization/67464
        PR rtl-optimization/67465
        * ifcvt.c (noce_try_cmove_arith): Bail out if cannot conditionally
        move in the mode of x.  Handle combination of complex and simple
        block pairs as well as the case when one is empty.

        * gcc.dg/pr67465.c: New test.
