diagnostic_show_locus adds a newline before doing anything (including
the do-nothing-else case).
This patch removes this initial newline, adding it to all callers
of diagnostic_show_locus instead.
Doing so makes diagnostic_show_locus more flexible, allowing it to be
used in my analyzer patch kit for printing diagnostic paths.

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.

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.

While looking at the vectorization for following example, we realized that
even though vectorizable_shift function was distinguishing vector shifted
by vector from vector shifted by scalar, while modelling the cost it would
always add the cost of building a vector constant despite not needing it for
vector shifted by scalar.
This patch fixes this by using scalar_shift_arg to determine whether we need
to build a vector for the second operand or not. This causes the test case
below to now vectorize.

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.

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.
