[PR81611] turn inc-and-use-of-dead-orig into auto-inc

When the addressing modes available on the machine don't allow offsets
in addresses, odds are that post-increments will be represented in
trees and RTL as:

  y <= x + 1
  ... *(x) ...
  x <= y

so deal with it by turning such RTL as:

  (set y (plus x n))
  ... (mem x) ...

without intervening uses of y into

  (set y x)
  ... (mem (post_add y n)) ...

so as to create auto-inc addresses that we'd otherwise miss.

[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.

-mindirect-branch=thunk-extern -O2 on x86-64 GNU/Linux generates:

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:
.LFB0:
.cfi_startproc
pushq %rbx
.cfi_def_cfa_offset 16
.cfi_offset 3, -16
movq (%rdi), %rax
movq %rdi, %rbx
movq 16(%rax), %rax
call __x86_indirect_thunk_rax
movq (%rbx), %rax
movq %rbx, %rdi
popq %rbx
.cfi_def_cfa_offset 8
movq 16(%rax), %rax
jmp __x86_indirect_thunk_rax
.cfi_endproc

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

Make fix for PR 83965 handle SLP reduction chains

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

[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 ?

PR 84519 Handle optional QUIET specifier for STOP and ERROR STOP

Fortran 2018 adds a new QUIET specifier for the STOP and ERROR STOP
statements, in order to suppress the printing of signaling FP
exceptions and the stop code. This patch adds the necessary library
changes, but for now the new specifier is not parsed and the frontend
unconditionally adds a false value for the new argument.

Regtested on x86_64-pc-linux-gnu.
