[AArch64] Use default_elf_asm_named_section instead of special cased hook

Hi,

The hook for TARGET_ASM_NAMED_SECTION was defined separately in
the backend around the time frame for GCC 4.7 under the assumption
that '@' would be used as a comment character in the binutils port.

This was indeed true in versions of the AArch64 port that never made it
into the FSF tree. However this practice was killed
before the binutils port made it upstream. Doing archaeology into
various revisions including the first commit of upstream binutils,
talking to Marcus about the history of this and actually testing the
first commit of binutils, I can confidently say that the upstream binutils
port never had any use of '@' as a comment character for AArch64
However we never got rid of the special cased handling in
GCC and the duplication of code in the AArch64 backend.

This was found when I was playing with Virtual Table verification
on ARM and AArch64 and discovered ICEs which were similar but manifested
in different places begging the obvious question.

Tested on aarch64-none-elf with no regressions.

Ok to apply ?

rs6000: Add "cannot_copy" attribute, use it (PR67788, PR67789)

After the shrink-wrapping patches the prologue will often be pushed
"deeper" into the function, which in turn means the software trace cache
pass will more often want to duplicate the basic block containing the
prologue.  This caused failures for 32-bit SVR4 with -msecure-plt PIC.

This configuration uses the load_toc_v4_PIC_1 instruction, which creates
assembler labels without using the normal machinery for that.  If now
the compiler decides to duplicate the insn, it will emit the same label
twice.  Boom.

It isn't so easy to fix this to use labels the compiler knows about (let
alone test that properly).  Instead, this patch wires up a "cannot_copy"
attribute to be used by TARGET_CANNOT_COPY_P, and sets that attribute on
these insns we do not want copied.

call scev analysis in scop-detection as in sese-to-poly

Before our rewrite of the scop detection, we used to not have a valid SESE
region under hand, and so we used to do more ad-hoc analysis of data references
by trying to prove that at all levels of a loop nest the data references would
be still valid.

Now that we have a valid SESE region, we can call the scev analysis in the same
way on the same computed loop nest in the scop-detection as in the sese-to-poly.

Next step will be to cache the data references analyzed in the scop detection
and not compute the same info in sese-to-poly.

The patch fixes block-1.f90 that used to ICE on x86_64-linux when compiled with
-m32.  Patch passed bootstrap with BOOT_CFLAGS="-g -O2 -fgraphite-identity

bb-reorder: Add -freorder-blocks-algorithm= and wire it up

This adds an -freorder-blocks-algorithm=[simple|stc] flag, with "simple"
as default.  For -O2 and up (except -Os) it is switched to "stc" instead.
Targets that never want STC can override this.  This changes -freorder-blocks
to be on at -O1 and up (was -O2 and up).

In effect, the changes are for -O1 (which now gets "simple" instead of
nothing), -Os (which now gets "simple" instead of "stc", since STC results
in much bigger code), and for targets that wish to never use STC (not in

[RS6000] Correct powerpc sysv stack argument accounting

ppc32 starts using the stack for integer arg passing when we run out
of integer arg passing registers.  Similarly, we start using the stack
for floating point args when we run out of floating point registers.
The decision on where an integer arg goes does not depend on number of
floating point args, nor does the decision on where a floating point
arg goes depend on number of integer args.  Alignment of stack args
also simply depends on number of stack args.

This patch untangles the horrible mess we had, with intarg_count being
wrongly used to count both integer args and stack words.

compiler: Accept untyped integral values as string/array indices.

    When determining the type of an index for a string/array indexing
    expression, the gofrontend would disallow floating-point and complex
    values even if they were integral and throw an internal error.  This
    patch changes gofrontend to use an integral type context when
    determining the types of a string/array index.

    Fixes golang/go#11545.

use MIN fusion for ISL-14

This patch fixes PR66754 by reverting an earlier unintended change.
We now generate a much simpler AST for interchange-1.c:

ISL AST generated by ISL:
{
  for (int c1 = 0; c1 <= 1334; c1 += 1) {
    S_7(c1);
    for (int c3 = 0; c3 <= 1334; c3 += 1)
      S_4(c1, c3);
    S_5(c1);
  }
  for (int c1 = 0; c1 <= 1334; c1 += 1)
    S_10(c1);
  S_8();
}

remove dead code of commutative_reductions

This code is not used anymore after we removed the previous loop optimizer (not
