PR 83036 Make NEXTREC specifier for INQUIRE work for large record numbers

This is accomplished by making the NEXTREC specifier be a 8 byte
integer where supported.

I wasn't able to come up with a testcase that does not create a large
file that could be added to the testsuite, but here's one which
creates a 2 GB file:

program nextrec
  implicit none
  integer(8) :: ii, n
  open(10, file="foo.dat", recl=1, access="direct", form="unformatted", &
       status="replace")
  do ii = 1, huge(1) + 2_8
     write(10, rec=ii) 'a'
  end do
  inquire(10, nextrec=n)
  if (n /= huge(1) + 3_8) then
     call abort()
  end if
  close(10, status="delete")
end program nextrec

Regtested on x86_64-pc-linux-gnu.
