[Bug fortran/34318] New: Modules: Infinity/NaN parameters read as 0.0

[burnus at gcc dot gnu dot org]

Split off of PR 34230.

Compile the following with -fno-range-check:

   module except
   real, parameter :: inf = 1./0., nan = 0./0.
   end module

   program a
     use except
     print *, inf, nan
   end program a

This prints:
   0.0000000       0.0000000

The .mod shows:
  (CONSTANT (REAL 4 0 0 REAL ()) 0 '0.@Inf@@47231941137967')
and                                 ^^^^^^^^
  (CONSTANT (REAL 4 0 0 REAL ()) 0 '0.@NaN@@47231941137967')
                                    ^^^^^^^^
