I totally botched up this sve test file in 259437.
It needs C++, so move it to g++.dg/other and make it a .C file.
Also adds the target guards to prevent it from running on non-aarch64 targets.
Tested that it passes on aarch64-none-elf and doesn't get run on arm-none-eabi.
Committing to trunk as obvious.

-fcf-protection -mcet can't be used with IFUNC features, like symbol
multiversioning or target clone, since IBT/SHSTK are applied to the whole
program and they may be disabled in some functions. But -fcf-protection
is implemented with multi-byte NOPs on all 64-bit processors as well as
32-bit processors starting with Pentium Pro. If -fcf-protection requires
-mcet, IFUNC features can't be used on Linux when -fcf-protection is
enabled by default.
This patch changes -fcf-protection to implement indirect branch and
return address tracking with multi-byte NOPs. -mibt and -mshstk are
changed to only enable CET built-in functions. CET tests are updated
to allow -fcf-protection without -mibt, -mshstk and -mcet on x86.
-fcf-protection=none are also added to tests which fail with
-fcf-protection so that -fcf-protection can be added to RUNTESTFLAGS
to verify -fcf-protection implementation.

tinst_level objects are created during template instantiation, and
they're most often quite short-lived, but since there's no intervening
garbage collection, they accumulate throughout the pass while most by
far could be recycled after a short while. The original testcase in
PR80290, for example, creates almost 55 million tinst_level objects,
all but 10 thousand of them without intervening GC, but we don't need
more than 284 of them live at a time.
Furthermore, in many cases, TREE_LIST objects are created to stand for
the decl in tinst_level. In most cases, those can be recycled as soon
as the tinst_level object is recycled; in some relatively common
cases, they are modified and reused in up to 3 tinst_level objects.
In the same testcase, TREE_LISTs are used in all but 3 thousand of the
tinst_level objects, and we don't need more than 89 tinst_level
objects with TREE_LISTs live at a time. Furthermore, all but 2
thousand of those are created without intervening GC.
This patch arranges for tinst_level objects to be refcounted (I've
seen as many as 20 live references to a single tinst_level object in
my testing), and for pending_template, tinst_level and TREE_LIST
objects that can be recycled to be added to freelists; that's much
faster than ggc_free()ing them and reallocating them shortly
thereafter. In fact, the introduction of such freelists is what makes
this entire patch lighter-weight, when it comes to memory use, and
faster. With refcounting alone, the total memory footprint was still
about the same, and we spent more time.
In order to further reduce memory use, I've arranged for us to create
TREE_LISTs lazily, only at points that really need them (when printing
error messages). This grows tinst_level by an additional pointer, but
since a TREE_LIST holds a lot more than an extra pointer, and
tinst_levels with TREE_LISTs used to be allocated tens of thousands of
times more often than plain decl ones, we still save memory overall.
I was still not quite happy about growing memory use in cases that
used template classes but not template overload resolution, so I
changed the type of the errors field to unsigned short, from int.
With that change, in_system_header_p and refcount move into the same
word or half-word that used to hold errors, releasing a full word,
bringing tinst_level back to its original size, now without any
padding.
The errors field is only used to test whether we've had any errors
since the expansion of some template, to skip the expansion of further
templates. If we get 2^16 errors or more, it is probably reasonable
to refrain from expanding further templates, even if we would expand
them before this change.
With these changes, compile time for the original testcase at -O0,
with default checking enabled, is cut down by some 3.7%, total GCable
memory allocation is cut down by almost 20%, and total memory use (as
reported by GNU time as maxresident) is cut down by slightly over 15%.

Bring in https://golang.org/cl/98616 from gc tip.
Original CL description:
This change modifies Go to disable loading of users' shell history for
TestTerminalSignal tests. TestTerminalSignal, as part of its workload,
will execute a new interactive bash shell. Bash will attempt to load the
user's history from the file pointed to by the HISTFILE environment
variable. For users with large histories that may take up to several
seconds, pushing the whole test past the 5 second timeout and causing
it to fail.
