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 ?

unconditionally adds a false value for the new argument.

nocf_check attribute can be used with -fcf-protection -mcet to disable
control-flow check by adding NOTRACK prefix before indirect branch.
When -mindirect-branch=thunk-extern -mindirect-branch-register is added,
indirect branch via register, "notrack call/jmp reg", is converted to
call/jmp __x86_indirect_thunk_nt_reg
When running on machines with CET enabled, __x86_indirect_thunk_nt_reg
can be updated to
notrack jmp reg
at run-time to restore NOTRACK prefix in the original indirect branch.
Since we don't support -mindirect-branch=thunk-extern, CET and MPX at
the same time, -mindirect-branch=thunk-extern is disallowed with
-fcf-protection=branch and -fcheck-pointer-bounds.
Tested on i686 and x86-64.

Due to there being no multilib mapping for Armv8-R, default multilib
builts for -march=armv4t with softfloat floating-point arithmetic is
being used. This patch maps it instead to the existing Armv7 multilibs.
Note that mapping for single-precision Armv8-R has been left out due to
there being no Arm implementation of that architecture variant.
