[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).
