[C] Add a target hook that allows targets to verify type usage
This patch adds a new target hook to check whether there are any
target-specific reasons why a type cannot be used in a certain
source-language context. It works in a similar way to existing
hooks like TARGET_INVALID_CONVERSION and TARGET_INVALID_UNARY_OP.
The reason for adding the hook is to report invalid uses of SVE types.
Throughout a TU, the SVE vector and predicate types represent values
that can be stored in an SVE vector or predicate register. At certain
points in the TU we might be able to generate code that assumes the
registers have a particular size, but often we can't. In some cases
we might even make multiple different assumptions in the same TU
(e.g. when implementing an ifunc for multiple vector lengths).
But SVE types themselves are the same type throughout. The register
size assumptions change how we generate code, but they don't change
the definition of the types.
This means that the types do not have a fixed size at the C level
even when -msve-vector-bits=N is in effect. It also means that the
size does not work in the same way as for C VLAs, where the abstract
machine evaluates the size at a particular point and then carries that
size forward to later code.
The SVE ACLE deals with this by making it invalid to use C and C++
constructs that depend on the size or layout of SVE types. The spec
refers to the types as "sizeless" types and defines their semantics as
edits to the standards. See:
https://gcc.gnu.org/ml/gcc-patches/2018-10/msg00868.html
for a fuller description and:
https://gcc.gnu.org/ml/gcc/2019-11/msg00088.html
for a recent update on the status.
However, since all current sizeless types are target-specific built-in
types, there's no real reason for the frontends to handle them directly.
They can just hand off the checks to target code instead. It's then
possible for the errors to refer to "SVE types" rather than "sizeless
types", which is likely to be more meaningful to users.
There is a slight overlap between the new tests and the ones for
gnu_vector_type_p in r277950, but here the emphasis is on testing
sizelessness.

Decouple constraints for u8path from path constructors
This patch moves helper classes and functions for std::filesystem::path out of
the class definition to a detail namespace so that they are available to the
implementations of std::filesystem::u8path. Prior to this patch, the SFINAE
constraints for those implementations were specified via delegation to the
overloads of path constructors with a std::locale parameter; it just so
happened that those overloads had the same constraints. As of P1423R3, u8path
and those overloads no longer have the same constraints, so this dependency
must be broken.
This patch also updates the experimental implementation of the filesystem TS
to add SFINAE constraints to its implementations of u8path. These functions
were previously unconstrained and marked with a TODO comment.
This patch does not provide any intentional behavioral changes other than the
added constraints to the experimental filesystem TS implementation of u8path.
Alternatives to this refactoring would have been to make the u8path overloads
friends of class path, or to make the helpers public members. Both of those
approaches struck me as less desirable than this approach, though this
approach does require more code changes and will affect implementation detail
portions of mangled names for path constructors and inline member functions
(mostly function template specializations).

Don't defer choice of vector type for bools (PR 92596)
Now that stmt_vec_info records the choice between vector mask
types and normal nonmask types, we can use that information in
vect_get_vector_types_for_stmt instead of deferring the choice
of vector type till later.
vect_get_mask_type_for_stmt used to check whether the boolean inputs
to an operation:
(a) consistently used mask types or consistently used nonmask types; and
(b) agreed on the number of elements.
(b) shouldn't be a problem when (a) is met. If the operation
consistently uses mask types, tree-vect-patterns.c will have corrected
any mismatches in mask precision. (This is because we only use mask
types for a small well-known set of operations and tree-vect-patterns.c
knows how to handle any that could have different mask precisions.)
And if the operation consistently uses normal nonmask types, there's
no reason why booleans should need extra vector compatibility checks
compared to ordinary integers.
So the potential difficulties all seem to come from (a). Now that
we've chosen the result type ahead of time, we also have to consider
whether the outputs and inputs consistently use mask types.
Taking each vectorizable_* routine in turn:
- vectorizable_call
vect_get_vector_types_for_stmt only handled booleans specially
for gassigns, so vect_get_mask_type_for_stmt never had chance to
handle calls. I'm not sure we support any calls that operate on
booleans, but as things stand, a boolean result would always have
a nonmask type. Presumably any vector argument would also need to
use nonmask types, unless it corresponds to internal_fn_mask_index
(which is already a special case).
For safety, I've added a check for mask/nonmask combinations here
even though we didn't check this previously.
- vectorizable_simd_clone_call
Again, vect_get_mask_type_for_stmt never had chance to handle calls.
The result of the call will always be a nonmask type and the patch
for PR 92710 rejects mask arguments. So all booleans should
consistently use nonmask types here.
- vectorizable_conversion
The function already rejects any conversion between booleans in which
one type isn't a mask type.
- vectorizable_operation
This function definitely needs a consistency check, e.g. to handle
& and | in which one operand is loaded from memory and the other is
a comparison result. Ideally we'd handle this via pattern stmts
instead (like we do for the all-mask case), but that's future work.
- vectorizable_assignment
VECT_SCALAR_BOOLEAN_TYPE_P requires single-bit precision, so the
current code already rejects problematic cases.
- vectorizable_load
Loads always produce nonmask types and there are no relevant inputs
to check against.
- vectorizable_store
vect_check_store_rhs already rejects mask/nonmask combinations
via useless_type_conversion_p.
- vectorizable_reduction
- vectorizable_lc_phi
PHIs always have nonmask types. After the change above, attempts
to combine the PHI result with a mask type would be rejected by
vectorizable_operation. (Again, it would be better to handle
this using pattern stmts.)
- vectorizable_induction
We don't generate inductions for booleans.
- vectorizable_shift
The function already rejects boolean shifts via type_has_mode_precision_p.
- vectorizable_condition
The function already rejects mismatches via useless_type_conversion_p.
- vectorizable_comparison
The function already rejects comparisons between mask and nonmask types.
The result is always a mask type.

libstdc++:: improve how pretty printers find node types (PR 91997)
This fixes two related problems.
The iterators for node-based containers use nested typedefs such as
std::list<T>::iterator::_Node to denote their node types. As reported in
https://bugzilla.redhat.com/show_bug.cgi?id=1053438 those typedefs are
not always present in the debug info. That means the pretty printers
cannot find them using gdb.lookup_type (via the find_type helper).
Instead of looking up the nested typedefs this patch makes the printers
look up the actual class templates directly.
A related problem (and the original topic of PR 91997) is that GDB fails
to find types via gdb.lookup_type when printing a backtrace from a
non-C++ functiion: https://sourceware.org/bugzilla/show_bug.cgi?id=25234
That is also solved by not looking up the nested typedef.

This patch simply punts on call arguments that have a mask type.
A better fix would be to pattern-match the comparison to a COND_EXPR,
like we would if the comparison was stored to memory, but doing that

Handle C2x attributes in Objective-C.
When adding the initial support for C2x attributes, I deferred the
unbounded lookahead support required to support such attributes in
Objective-C (except for the changes to string literal handling, which
were the riskier piece of preparation for such lookahead support).
This patch adds that remaining ObjC support.
For C, the parser continues to work exactly as it did before. For
ObjC, however, when checking for whether '[[' starts attributes, it
lexes however many tokens are needed to check for a matching ']]', but
in a raw mode that omits all the context-sensitive processing that
c_lex_with_flags normally does, so that that processing can be done
later when the right context-sensitive flags are set. Those tokens
are saved in a separate raw_tokens vector in the parser, and normal
c_lex_one_token calls will get tokens from there and perform the
remaining processing on them, if any tokens are found there, so all
parsing not using the new interfaces gets the same tokens as it did
before. (For C, this raw lexing never occurs and the vector of raw
tokens is always NULL.)
Bootstrapped with no regressions for x86_64-pc-linux-gnu.

Update vect_char_add target selector to use its own cache
This patch updates the vect_char_add target selector to use its own
cache instead of the vect_int cache.
This was causing a situation where bb-slp-40.c would fail on sparc when
run after other tests that use the vect_int target selector, but pass
when run on its own.
