c++: Testsuite adjustments for PR 90992.

It occurred to me that the NotNoexcept class is irrelevant to the issue I
was fixing, so let's remove it.

c++: Fix -Wnoexcept handling of system headers (PR90992).

The immediate issue here was that the second warning didn't depend on the
first one, so if the first location was in a system header, we'd
mysteriously give the second by itself.

It's also the case that the thing we care about being in a system header is
the function that we want to suggest adding 'noexcept' to, not the
noexcept-expression; it's useful to suggest adding noexcept to a user
function to satisfy a noexcept-expression in a system header.

In the *{add,sub}v<dwi>4_doubleword patterns, we don't really want to see a
VOIDmode last operand, because it then means invalid RTL
(sign_extend:{TI,POI} (const_int ...)) or so, and therefore something we
don't really handle in the splitter either.  We have
*{add,sub}v<dwi>4_doubleword_1 pattern for those and that is what combine
will match, the problem in this testcase is just that it was only RA that
propagated the constant into the instruction.

Apparently my recent patch which moved the *avx_vperm_broadcast* and

define_insn_and_split matched always but the splitter condition only split
it if not -mavx2 for V4DFmode, basically relying on the vpermpd pattern to
come first.

The following patch fixes it by moving that part of SPLIT-CONDITION into
CONDITION, so that when it is not met, we just don't match the pattern

i386: prefer vpermilpd over vpermpd [PR93395]

In Agner Fog's tables, vpermilp[sd] with immediates seem to be
much faster than vpermpd with immediate, for a good reason,
the former only permute something within the lanes and don't do anything
intra-lane, while vpermpd can.  So, functionality-wise, vpermilpd
is more efficient subset of vpermpd.  We use the same RTL for those
though (and also for certain broadcast).

Now, the problem was that the vpermpd pattern appeared first in sse.md,
followed by the broadcast patterns, followed by the vpermilp[sd].
Which means unless -mavx -mno-avx2, we'd emit vpermpd instead of the
more efficient alternatives.

The following patch reorders them, so that vpermpd comes last, if we
can match a broadcast, we do, if we can match a vpermilp[sd] that is not a
broadcast, we will, otherwise fall back (of course only if -mavx2) to
vpermpd.

c++: Fix ICE in tsubst_copy with parenthesized expression [PR93299]

Since e4511ca2e9ecdb51d41b64452398f8e2df575668 force_paren_expr can create
a VIEW_CONVERT_EXPR so that we have something to set REF_PARENTHESIZED_P

with such a VIEW_CONVERT_EXPR, because it's not location_wrapper_p, or
a TEMPLATE_PARM_INDEX wrapped in a VIEW_CONVERT_EXPR.

contrib: Change 'remote' for personal branches and add branch creation script

Whilst trying to convert the add vendor branch script to work with
personal branches I encountered a minor issue where git would report
ambiguous refs when checking out the new branch.

It turns out that this is because git considers <me>/<topic> to be
ambiguous if both

  refs/heads/<me>/<topic>

and

  refs/remotes/<me>/<topic>

exist in the list of known branches.

Having thought about this a bit, I think the best solution is to adopt
something more like the vendors space and call the remote users/<me>
(this also works better if you want to set up remotes to track other
users branches as well).

So this patch has two parts.

1) It updates gcc-git-customization.sh to set up the new 'remote' and
converts any existing remote and branches tracking that to the new
format
2) It adds a new script to set up a personal branch on the gcc git repository.

* gcc-git-customization.sh: Use users/<pfx> for the personal remote
rather than just <pfx>.  Convert any existing personal branches to the
new remote.
* git-add-user-branch.sh: New file.

Provide means, in the form of a `--with-toolexeclibdir=' configuration
option, to override the default installation directory for target
libraries, otherwise known as $toolexeclibdir.  This is so that it is

i386: Fix ICEs on TImode signed overflow add/sub patterns [PR93376]

(insn 18 17 19 2 (parallel [

        (const_wide_int 0x7fffffffffffffffffffffffffffffff)) "pr93376.c":8:10 65 {*movti_internal}
     (nil))
the eq in there gets simplified into:
(eq:CCO (const_wide_int 0x080000000000000000000000000000000)
    (const_wide_int 0x80000000000000000000000000000000))
and simplify-rtx.c tries to simplify it by simplifying MINUS
of the two operands.
Now, i386 defines MAX_BITSIZE_MODE_ANY_INT to 128, because OImode
and XImode are used mainly as a placeholder for the vector modes;
these new signed overflow patterns are an exception to that,
but what they really need is just TImode precision + 1 (maybe 2 worst case)
bits at any time.

wide-int.h defines WIDE_INT_MAX_ELTS in a way that it contains one more
HWI above number of HWIs to cover WIDE_INT_MAX_ELTS, so on i386 that is
3 HWIs, meaning that TImode precision + 1/2 bits is still representable in
there.  Unfortunately, the way wi::sub_large is implemented, it needs
not just those 3 HWIs, but one HWI above the maximum of the lengths of
both operands, which means it buffer overflows, overwrites the following
precision in wide_int_storage and ICEs later on.  The need for 4 HWIs is
only temporary, because canonize immediately after it canonicalizes it
back to 3 HWIs only.

The patch is something suggested by Richard S., avoid using OImode
for this and instead use a partial int mode that is smaller.

libstdc++: Simplify makefile rule for largefile-config.h (PR91947)

The previous rule could leave an incomplete file if the build was
interrupted, which would then not be remade if make was run again.

This makes the rule more robust by writing to a temporary file and only
moving it into place as the final step. It also simplifies the rule so
that only the essential macro definitions are written to the file, not
the explanatory comments and commented out #undef lines.

Also, the macro for enabling LFS on Mac OS X 10.5 is now set
unconditionally, which is a bug fix from upstream autoconf.

aarch64: Fix -mtrack-speculation for irreversible conditions [PR93341]

We can't yet represent the inverse of all conditions in rtl
(see g:865257c447cc50f5819e), triggering an ICE in the pass
that handles -mtrack-speculation.  Since we don't expect these
insns to be optimised in any way, the easiest fix seemed to be
to add an insn that reverses the condition internally.

gotest: explicitly skip type descriptors

Type descriptors are normally weak and nm will report them as V,
so we will skip them when collecting the list of symbols.
But when not using GNU nm, they may be reported as D,
so also skip them in symstogo.

This fixes go/doc/check on Solaris.

analyzer: fix ICE due to sm-state origin being purged (PR 93382)

The ICE in PR analyzer/93382 is a validation error.

The global variable "idx" acquires a "tainted" state from local array
n1[0].  When the frame is popped, the svalue for n1[0] is purged, but
the "taint" sm_state_map's entry for "idx" has a svalue_id referencing
the now-purged svalue.  This is caught by program_state::validate as an
assertion failure.

This patch fixes the issue by resetting the origin id within
sm_state_map entries for the case where the origin id has been purged.

causing default dg-do to be set incorrectly on most targets.
Instead move testcases that are vect related testcase that
use "dg-require-effective-target vect_*" to the vect test area.

blender in SPEC is built with -funsigned-char, which is also the default on
PPC, and exposed -Wsign-conversion issues that weren't seen by the x86_64

that we didn't't previously complain about as a whole.  So only check
operands after we check the whole expression.  Also, to fix the PR 40752

analyzer: fix setjmp handling with -g (PR 93378)

PR analyzer/93378 reports an ICE at -O1 -g when analyzing a rewind via
longjmp to a setjmp call with.

The root cause is that the rewind_info_t::get_setjmp_call attempts to
locate the setjmp GIMPLE_CALL via within the exploded_node containing
it, but the exploded_node has two stmts: a GIMPLE_DEBUG, then the
GIMPLE_CALL, and so erroneously picks the GIMPLE_DEBUG, leading to
a failed as_a <const gcall *>.

This patch reworks how the analyzer stores information about a setjmp
so that instead of storing an exploded_node *, it instead introduces
a "setjmp_record" struct, for use by both setjmp_svalue and
rewind_info_t.  Hence we store the information directly, rather than
attempting to reconstruct it, fixing the bug.

cfgexpand: Update partition size when merging variables

cfgexpand sorts variables by decreasing size, so when merging a later
variable into an earlier one, there's usually no need to update the
merged size.

But for poly_int sizes, the sort function just uses a lexicographical
comparison of the coefficients, so e.g. 2X+2 comes before 0X+32.
Which is bigger depends on the runtime value of X.

This patch therefore takes the upper bound of the two sizes, which
is conservatively correct for variable-length vectors and a no-op
on other targets.

It's probably a bad idea to merge fixed-length and variable-length
variables in practice, but that's really an optimisation decision.
I think we should have this patch as a correctness fix either way.

This is easiest to test using the ACLE, but in principle it could happen
for autovectorised code too, e.g. when using OpenMP vector variables.
It's therefore a regression from GCC 8.
