Now that the ABI supports large record lengths, there's a few places
in libgfortran where we need to use larger types. For internal units
which by definition are in-memory, it's enought to use ptrdiff_t, for
external units gfc_offset.

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

From-SVN: r254908

Expand the gtm_jmpbuf structure by one word field to add
Intel CET support further. The code in sjlj.S already
allocates more space on the stack then gtm_jmpbuf needs.
Use this extra space to absorb the new field.

The structure is allocated on the stack in such a way
that eip/rsp field is overlapped with return address on
the stack. Locate the new field right before eip/rsp so
code that accesses buffer fields relative to address of
gtm_jmpbuf has its offsets unchanged.

	* libitm/config/x86/target.h: Add new field (ssp).
	* libitm/config/x86/sjlj.S: Change offsets.
