New tests
This patch adds new tests to validate new deleted overloads of wchar_t,
char8_t, char16_t, and char32_t for ordinary and wide formatted character and
string ostream inserters.
Additionally, new tests are added to validate invocations of u8path with
sequences of char8_t for both the C++17 and filesystem TS implementations.

Update feature test macro, add deleted operators, update u8path
This patch increments the __cpp_lib_char8_t feature test macro, adds deleted
operator<< overloads for basic_ostream, and modifies u8path to accept
sequences of char8_t for both the C++17 implementation of std::filesystem, and
the filesystem TS implementation.
The implementation mechanism used for u8path differs between the C++17 and
filesystem TS implementations. The changes to the former take advantage of
C++17 'if constexpr'. The changes to the latter retain C++11 compatibility
and rely on tag dispatching.

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).

The function maybe_resimplify_conditional_op uses operation_could_trap_p to
check if the resulting operation of a simplification can trap. Because of the
changes introduced by revision r276659, this results in an ICE due to a
violated assertion in operation_could_trap_p if the operation is a COND_EXPR or
a VEC_COND_EXPR. The changes have allowed those expressions to trap and
whether they do cannot be determined without considering their condition
which is not available to operation_could_trap_p.
Change maybe_resimplify_conditional_op to inspect the condition of
COND_EXPRs and VEC_COND_EXPRs to determine if they can trap.

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.

search_type_for_mask uses a worklist to search a chain of boolean
operations for a natural vector mask type. This patch instead does
that in vect_determine_stmt_precisions, where we also look for
overpromoted integer operations. We then only need to compute
the precision once and can cache it in the stmt_vec_info.
The new function vect_determine_mask_precision is supposed
to handle exactly the same cases as search_type_for_mask_1,
and in the same way. There's a lot we could improve here,
but that's not stage 3 material.
I wondered about sharing mask_precision with other fields like
operation_precision, but in the end that seemed too dangerous.
We have patterns to convert between boolean and non-boolean
operations and it would be very easy to get mixed up about

vect_recog_bool_pattern assumed that a comparison between two booleans
should always become a comparison of vector mask types (implemented as an
XOR_EXPR). But if the booleans in question are generated as data values
(e.g. because they're loaded directly from memory), we should treat them
like ordinary integers instead, just as we do for boolean logic ops whose
operands are loaded from memory. vect_get_mask_type_for_stmt already
handled this case:
/* We may compare boolean value loaded as vector of integers.

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.

In this PR we assigned a vector mask type to the result of a comparison
and then tried to pass that mask type to a simd clone, which expected
a normal (non-mask) type instead.
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
isn't gcc 9 or 10 material.
Note that this doesn't affect x86_64-linux-gnu because the ABI promotes

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.)

The asm-flag-4.c test forces the generation of Thumb code for armv4t,
which is not supported when using the 'hard' FP ABI. This patch
ensures the test uses -mfloat-abi=softfp safely, to avoid irrelevant
failures.
