  -----------
  [ComplexDeinterleave] Don't try to combine single FP reductions. (#139469)

Currently the apss tries to combine floating point reductions, without
checking for the correct fast-math flags and it also creates invalid IR
(using llvm.reduce.add for FP types).

For now, just bail out for non-integer types.
