Add OpenACC 2.6 `serial' construct support
The `serial' construct (cf. section 2.5.3 of the OpenACC 2.6 standard)
is equivalent to a `parallel' construct with clauses `num_gangs(1)
num_workers(1) vector_length(1)' implied.
These clauses are therefore not supported with the `serial'
construct. All the remaining clauses accepted with `parallel' are also
accepted with `serial'.
The `serial' construct is implemented like `parallel', except for
hardcoding dimensions rather than taking them from the relevant
clauses, in `expand_omp_target'.
Separate codes are used to denote the `serial' construct throughout the
middle end, even though the mapping of `serial' to an equivalent
`parallel' construct could have been done in the individual language
frontends. In particular, this allows to distinguish between compute
constructs in warnings, error messages, dumps etc.

Fix SLP downward group access classification (PR92420)
This PR was caused by the SLP handling in get_group_load_store_type
returning VMAT_CONTIGUOUS rather than VMAT_CONTIGUOUS_REVERSE for
downward groups.
A more elaborate fix would be to try to combine the reverse permutation
into SLP_TREE_LOAD_PERMUTATION for loads, but that's really a follow-on
optimisation and not backport material. It might also not necessarily
be a win, if the target supports (say) reversing and odd/even swaps
as independent permutes but doesn't recognise the combined form.

[rs6000] Make load cost a bit more in vectorization cost
To align with rs6000_insn_cost costing more for load type insns,
this patch is to make load insns cost more in vectorization cost
function. The latency of load insns is about twice that of
"simple" instructions; 2 vs. 1 on older cores, and 4 (or so) vs.
2 on newer cores. Considering that the result of load usually
is used somehow later (true-dep) but store won't, we keep the
store as before.
The SPEC2017 performance evaluation on Power8 shows 525.x264_r
+9.56%, 511.povray_r +2.08%, 527.cam4_r 1.16% gains, no
significant degradation, SPECINT geomean +0.88%, SPECFP geomean

[C] Opt out of GNU vector extensions for built-in SVE types
The AArch64 port defines built-in SVE types at start-up under names
like __SVInt8_t. These types are represented in the front end and
gimple as normal VECTOR_TYPEs and are code-generated as normal vectors.
However, we'd like to stop the frontends from treating them in the
same way as GNU-style ("vector_size") vectors, for several reasons:
(1) We allowed the GNU vector extensions to be mixed with Advanced SIMD
vector types and it ended up causing a lot of confusion on big-endian
targets. Although SVE handles big-endian vectors differently from
Advanced SIMD, there are still potential surprises; see the block
comment near the head of aarch64-sve.md for details.
(2) One of the SVE vectors is a packed one-bit-per-element boolean vector.
That isn't a combination the GNU vector extensions have supported
before. E.g. it means that vectors can no longer decompose to
arrays for indexing, and that not all elements are individually
addressable. It also makes it less clear which order the initialiser
should be in (lsb first, or bitfield ordering?). We could define
all that of course, but it seems a bit weird to go to the effort
for this case when, given all the other reasons, we don't want the
extensions anyway.
(3) The GNU vector extensions only provide full-vector operations,
which is a very artifical limitation on a predicated architecture
like SVE.
(4) The set of operations provided by the GNU vector extensions is
relatively small, whereas the SVE intrinsics provide many more.
(5) It makes it easier to ensure that (with default options) code is
portable between compilers without the GNU vector extensions having
to become an official part of the SVE intrinsics spec.
(6) The length of the SVE types is usually not fixed at compile time,
whereas the GNU vector extension is geared around fixed-length
vectors.
It's possible to specify the length of an SVE vector using the
command-line option -msve-vector-bits=N, but in principle it should
be possible to have functions compiled for different N in the same
translation unit. This isn't supported yet but would be very useful
for implementing ifuncs. Once mixing lengths in a translation unit
is supported, the SVE types should represent the same type throughout
the translation unit, just as GNU vector types do.
However, when -msve-vector-bits=N is in effect, we do allow conversions
between explicit GNU vector types of N bits and the corresponding SVE
types. This doesn't undermine the intent of (5) because in this case
the use of GNU vector types is explicit and intentional. It also doesn't
undermine the intent of (6) because converting between the types is just
a conditionally-supported operation. In other words, the types still
represent the same types throughout the translation unit, it's just that
conversions between them are valid in cases where a certain precondition
is known to hold. It's similar to the way that the SVE vector types are
defined throughout the translation unit but can only be used in functions
for which SVE is enabled.
The patch adds a new flag to tree_type_common to select this behaviour.
(We currently have 17 bits free.) To avoid making the flag too specific
to vectors, I called it TYPE_INDIVISIBLE_P, to mean that the frontend
should not allow the components of the type to be accessed directly.
This could perhaps be useful in future for hiding the fact that a
type is an array, or for hiding the fields of a record or union.
The actual frontend changes are very simple, mostly just replacing
VECTOR_TYPE_P with gnu_vector_type_p in selected places.
One interesting case is:
/* Need to convert condition operand into a vector mask. */
if (VECTOR_TYPE_P (TREE_TYPE (ifexp)))
{
tree vectype = TREE_TYPE (ifexp);
tree elem_type = TREE_TYPE (vectype);
tree zero = build_int_cst (elem_type, 0);
tree zero_vec = build_vector_from_val (vectype, zero);
tree cmp_type = build_same_sized_truth_vector_type (vectype);
ifexp = build2 (NE_EXPR, cmp_type, ifexp, zero_vec);
}
in build_conditional_expr. This appears to be trying to support
elementwise conditions like "vec1 ? vec2 : vec3", which is something
the C++ frontend supports. However, this code can never trigger AFAICT,
because "vec1" does not survive c_objc_common_truthvalue_conversion:
case VECTOR_TYPE:
error_at (location, "used vector type where scalar is required");
return error_mark_node;
Even if it did, the operation should be a VEC_COND_EXPR rather
than a COND_EXPR.
I've therefore left that condition as-is, but added tests for the
"vec1 ? vec2 : vec3" case to make sure that we don't accidentally
allow it for SVE vectors in future.

Generalise gather and scatter optabs
The gather and scatter optabs required the vector offset to be
the integer equivalent of the vector mode being loaded or stored.
This patch generalises them so that the two vectors can have different
element sizes, although they still need to have the same number of
elements.
One consequence of this is that it's possible (if unlikely)
for two IFN_GATHER_LOADs to have the same arguments but different
return types. E.g. the same scalar base and vector of 32-bit offsets
could be used to load 8-bit elements and to load 16-bit elements.
From just looking at the arguments, we could wrongly deduce that
they're equivalent.
I know we saw this happen at one point with IFN_WHILE_ULT,
and we dealt with it there by passing a zero of the return type
as an extra argument. Doing the same here also makes the load
and store functions have the same argument assignment.
For now this patch should be a no-op, but later SVE patches take
advantage of the new flexibility.

Handle removal of old-style function definitions in C2x.
C2x removes support for old-style function definitions with identifier
lists, changing () in function definitions to be equivalent to (void)
(while () in declarations that are not definitions still gives an
unprototyped type).
This patch updates GCC accordingly. The new semantics for () are
implemented for C2x mode (meaning () in function definitions isn't
diagnosed by -Wold-style-definition in that mode).
-Wold-style-definition is enabled by default, and turned into a
pedwarn, for C2x.
Bootstrapped with no regressions on x86_64-pc-linux-gnu.
gcc:
* doc/invoke.texi (-Wold-style-definition): Document () not being
considered an old-style definition for C2x.
gcc/c:
* c-decl.c (grokparms): Convert () in a function definition to
(void) for C2x.
(store_parm_decls_oldstyle): Pedwarn for C2x.
(store_parm_decls): Update comment about () not generating a
prototype.
gcc/c-family:
* c.opt (Wold-style-definition): Initialize to -1.
* c-opts.c (c_common_post_options): Set warn_old_style_definition
to flag_isoc2x if not set explicitly.
