[Bug fortran/32969] New: (rr)?spacing give wrong answers with -fdefault-integer-8

[dominiq at lps dot ens dot fr]

With -fdefault-integer-8 the following code:

program test_rrspacing
  real x
  x = 3.0
  x = rrspacing(x)
  print *, x, spacing(x), spacing(3.0)
  x = 3.0
  x = spacing(x)
  print *, x
end

gives:

  0.7500000      1.6777216E+07  2.3841858E-07
  1.6777216E+07

instead of

  1.2582912E+07   1.000000      2.3841858E-07
  2.3841858E-07

Note that like PR32933 the code does not involve directly integers and as in
the original test of PR32770 it seems to be linked to bigendian platforms (PPC
here).

Should be fixed on trunk.  No back port.
