[Patch AArch64] Turn on frame pointer / partial fix for PR84521
This fixes a GCC-8 regression that we accidentally switched off frame
pointers in the AArch64 backend when changing the defaults in the common
parts of the code. This breaks an ABI decision that was made in GCC at
the dawn of the port with respect to having a frame pointer at all
times. If we really want to turn this off lets have a discussion around
that separately.
For now turn this back on and I believe this will leave PR84521 latent
again with -fomit-frame-pointer and (hopefully) make the ruby issue go
away. I'm asking Sudi to pick that up.
Bootstrapped and regression tested on AArch64-none-linux-gnu but I see
one regression in gcc.c-torture/execute/960419-2.c which needs to be
looked at next (PR84528, thanks Kyrill).
Ok to put in and then look at PR84528 ?

Character length cleanup for Coarray Fortran library
Following the change to use size_t for Fortran character lengths (PR
78534), this patch modifies the Coarray ABI in a similar way. The
single-image implementation that is included in libgfortran is
updated, but this needs corresponding work in the OpenCoarray library
as well for multi-image support. I also fixed the types for the STOP
and ERROR STOP implementation in libgfortran, as the calling of them
is somewhat intertwined with the calling of the corresponding CAF
functions. I'll send the OpenCoarray changes as a separate pull
request to the OpenCoarrays repository.

c++: Fix spurious fallthrough warning on break
The C++ frontend generates a break that results in the fallthrough
warning misfiring in nested switch blocks where cases in the inner
switch block return, rendering the break pointless. The fallthrough
detection in finish_break_stmt does not work either because the
condition is encoded as an IF_STMT and not a COND_EXPR.
Fix this by adding a condition for IF_STMT in the
langhooks.block_may_fallthru for C++. Fix tested on x86_64.
