Replace label_text ctor with "borrow" and "take"
libcpp's label_text class wraps a text buffer, along with a flag to
determine if it "owns" the buffer.
The existing ctor exposed this directly, but I found it difficult
to remember the sense of flag, so this patch hides the ctor, in
favor of static member functions "borrow" and "take", to make
the effect on ownership explicit in the name.

diagnostic_show_locus adds a newline before doing anything (including

Fix libdecnumber handling of non-canonical BID significands (PR middle-end/91226).
As reported in bug 91226, the libdecnumber code used on the host to
interpret DFP values in the BID encoding fails, for _Decimal64 and
_Decimal128, to check for the case where a significand is too large
and so specified in IEEE 754 to be a non-canonical encoding of the
zero significand. This patch adds the required handling of that case,
together with tests both using -O2 (testing this host code) and -O0
(testing libgcc code, which already worked before the patch); the
tests also cover _Decimal32, which already had the required check.
In the _Decimal128 case, where the code previously completely ignored
the case where the first four bits of the combination field are 1100,
1101 or 1110, the logic for determining the correct quantum exponent
in that case is also newly added by this patch, so tests are added for
that as well (again, libgcc already handled it correctly when the
conversion was done at runtime rather than at compile time).
Bootstrapped with no regressions for x86_64-pc-linux-gnu.

[mid-end] Add notes to dataflow insn info when re-emitting (PR92410)
In scheduling passes, notes are removed with `remove_notes` before the
scheduling is done, and added back in with `reemit_notes` once the
scheduling has been decided.
This process leaves the notes in the RTL chain with different insn uid's
than were there before. Having different UID's (larger than the
previous ones) means that DF_INSN_INFO_GET(insn) will access outside of
the allocated array.
This has been seen in the `regstat_bb_compute_calls_crossed` function.
This patch adds an assert to the `regstat_bb_compute_calls_crossed`
function so that bad accesses here are caught instead of going
unnoticed, and then avoids the problem.
We avoid the problem by ensuring that new notes added by `reemit_notes` have an
insn record given to them. This is done by adding a call to
`df_insn_create_insn_record` on each note added in `reemit_notes`.
`df_insn_create_insn_record` leaves this new record zeroed out, which appears
to be fine for notes (e.g. `df_bb_refs_record` already does not set
anything except the luid for notes, and notes have no dataflow information to
record).
We add the testcase that Martin found here
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92410#c2 .
This testcase fails with the "regstat.c" change, and then succeeds with the
"haifa-sched.c" change.
There is a similar problem with labels, that the `gcc_assert` catches
when running regression tests in gcc.dg/fold-eqandshift-1.c and
gcc.c-torture/compile/pr32482.c.
This is due to the `cfg_layout_finalize` call in `bb-reorder.c` emitting
new labels, and these labels not having a dataflow df_insn_info member.
We solve this by manually calling `df_recompute_luids` on each basic
block once this pass has finished.
Testing done:
Ran regression tests on aarch64-none-linux-gnu cross compiler.
Bootstrapped and ran tests on aarch64-none-linux-gnu native.

always add the cost of building a vector constant despite not needing it for

Fix overflows in -fprofile-reorder-functions
This patch fixes three sissues with -fprofile-reorder-functions:
1) First is that tp_first_run is stored as 32bit integer while it can easily
overflow (and does so during Firefox profiling).
2) Second problem is that flag_profile_functions can
not be tested w/o function context.
The changes to expand_all_functions makes it to work on mixed units by
first outputting all functions w/o -fprofile-reorder-function (or with no
profile info) and then outputting in first_run order
3) LTO partitioner was mixing up order by tp_first_run and by order.
for no_reorder we definitly want to order via first, while for everything
else we want to roder by second.
I have also merged duplicated comparators since they are bit fragile into
tp_first_run_node_cmp.
I originaly started to look into this because of undefined symbols with
Firefox PGO builds. These symbols went away with fixing these bug but I am not
quite sure how. it is possible that there is another problem in lto_blanced_map
but even after reading the noreorder code few times carefuly I did not find it.
Other explanation would be that our new qsort with broken comparator due to
overflow can actualy remove some entries in the array, but that sounds bit
crazy.

PR c++/91678 - wrong error with decltype and location wrapper.
Compiling this testcase results in a bogus "invalid cast" error; this occurs
since the introduction of location wrappers in finish_id_expression.
Here we are parsing the decltype expression via cp_parser_decltype_expr which
can lead to calling various fold_* and c-family routines. They use
non_lvalue_loc, but that won't create a NON_LVALUE_EXPR wrapper around a location
wrapper.
So before the location wrappers addition cp_parser_decltype_expr would return
NON_LVALUE_EXPR <c>. Now it returns VIEW_CONVERT_EXPR<float *>(c), but the
STRIP_ANY_LOCATION_WRAPPER immediately following it strips the location wrapper,
and suddenly we don't know whether we have an lvalue anymore. And that's sad
because then decltype produces the wrong type, causing nonsense errors.

Fix @multitable handling in texi2pod.pl
While trying out Dennis's Armv8.6-A patch, I noticed that texi2pod.pl
didn't handle the new @multitable correctly. There were two problems:
(1) @multitables nested in other @tables inherited the @item type from
the enclosing @table. Since the new @multitable is in a @table @samp,
we applied @samp markup to the @multitable @items. This in turn
meant that it captured the @tab separator in the @item markup.
Fixed by pushing an empty item code onto the stack.
(2) We didn't handle @headitem. Fixed by enclosing it in italics,
like we do for section headings. This causes it to be underlined
in the man output.

Avoid quadratic behaviour in prune_runtime_alias_test_list
prune_runtime_alias_test_list used ordered_remove to remove a merged
alias pair, which made the function quadratic when many aliases could
be removed.
I had a testcase in which these memmoves accounted for an impressive
85% of compile time. The fact that we had so many probably shows
a deeper problem, but still, it's easy to remove as we go.

Fix g++.dg/torture/pr59226.C
this patch fixes ICE in g++.dg/torture/pr59226.C which was triggered by
new comdat_local sanity check. What happens here is that function gets
inlined into its own thunk which makes it !comdat_local_p but the updating
code does not notice since thunk calls comdat local alias of the function
itself and we look at alias target rather than original callee.
This also shows that we miss optimization here. Currently we will not inline
thunk out of its comdat local group w/o inlining function it is associated with
into it.
We should teach inline_call to reoslve edges to aliases while inlining and
relax calls_comdat_local flag. But this needs bit more work, so I fix the
ICE first.
