[IEPM] don't preserve lexical blocks just for debug inline markers
This patch stops preserving scope blocks just because they are inlined
function scopes, when cleaning up unused scope blocks. This change
was introduced along with IEPM, but it preserved lots of blocks, and
output debug information for them, although no code from the inlined
function remained after optimization.
The additional preserved blocks took up compile-time memory, and
significant disk space and link time, in some cases more than 25%.
This is deemed excessive, compared with the reasonably small benefit
of allowing one to single-step into an inlined function using a
view-capable debugger.
There was another way of marking inlined function scopes as unused,
based on the markers referencing them during stmt scanning, but that
still preserved too much.
So, this patch restores the pre-IEPM logic of preservation of scopes.
Should a scope block referenced by an inline entry marker be found to
be unused in remove_unused_scope_block_p, the marker will be cleaned
up right after that, in clear_unused_block_pointer, so we won't keep
a dangling reference to a dropped block.

x86-64 is supposed to have asynchronous unwind tables by default, but
there is nothing that reflects the change in the (relative) frame
address after .LIND0. That region really has to be moved outside of
the .cfi_startproc/.cfi_endproc bracket.
This patch adds TARGET_INDIRECT_BRANCH_REGISTER to force indirect
branch via register whenever -mindirect-branch= is used. Now,
-mindirect-branch=thunk-extern -O2 on x86-64 GNU/Linux generates:
_Z1fP1C:

.cfi_def_cfa_offset 8
movq 16(%rax), %rax
jmp __x86_indirect_thunk_rax

so that "-mindirect-branch=thunk-extern" is equivalent to
"-mindirect-branch=thunk-extern -mindirect-branch-register", which is
used by Linux kernel.

This patch prevents pattern-matching of fold-left SLP reduction chains,
which the previous patch for 83965 didn't handle properly. It only
stops the last statement in the group from being matched, but that's
enough to cause the group to be dissolved later.
A better fix would be to put all the information about the reduction
on the the first statement in the reduction chain, so that every
statement in the group can tell what the group is doing. That doesn't
seem like stage 4 material though.

[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 ?

i386: Add __x86_indirect_thunk_nt_reg for -fcf-protection -mcet
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

-fcf-protection=branch and -fcheck-pointer-bounds.

Due to there being no multilib mapping for Armv8-R, default multilib

Note that mapping for single-precision Armv8-R has been left out due to
