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.

Regtested on x86_64-pc-linux-gnu?

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

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.

Disabling software prefetching and switching the autoprefetcher to weak improves
CPU2017 rate and speed benchmarks for both int and fp sets on Falkor.

SPECrate 2017 fp is up 0.38%
SPECspeed 2017 fp is up 0.54%
SPECrate 2017 int is up 3.02%
SPECspeed 2017 int is up 3.16%

There are only a couple individual regressions. The biggest one being about 4%
in parest.

For SPEC2006, we've noticed the following:

SPECint is up 0.91%
SPECfp is stable

In the case of SPEC2006 we noticed both a big regression in mcf (about 20%)
and a big improvement for hmmer (about 40%).

Since the overall result is positive, we would like to make these new tuning
settings the default for Falkor.

We may revisit the software prefetcher setting in the future, in case we
can adjust it enough so it provides us a good balance between improvements and
regressions (mcf). But for now it is best if it stays off.
