In various places we use lookup_name_fuzzy to provide a hint,
and can report messages of the form:
  error: unknown foo named 'bar'
or:
  error: unknown foo named 'bar'; did you mean 'SUGGESTION?

This patch provides a way for lookup_name_fuzzy to provide
both the suggestion above, and (optionally) additional hints
that can be printed e.g.

  note: did you forget to include <SOME_HEADER.h>?

This patch provides the mechanism and ports existing users
of lookup_name_fuzzy to the new return type.
There are no uses of such hints in this patch, but followup
patches provide various front-end specific uses of this.

Expanders for Armv8-M nonsecure call unnecessarily clobber r4 despite
the libcall they perform not writing to r4.  Furthermore, the
requirement for the branch target address to be in r4 as expected by
the libcall is modeled in a convoluted way in the define_insn patterns:
the address is a register match_operand constrained by the match_dup
for the clobber which is guaranteed to be r4 due to the expander.

This patch simplifies all this by simply requiring the address to be in
r4 and removing the clobbers. Expanders are left alone because
cmse_nonsecure_call_clear_caller_saved relies on branch target memory
attributes which would be lost if expanding to reg:SI R4_REGNUM.

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
