The pr99023 testcase uses --param=ggc-min-expand=0 which forces a GC
during every collection point and consequently is very slow to run,
and ends up being the main bottleneck of the modules.exp testsuite.
So this patch restricts this test to run once, in C++20 mode, instead of
multiple times (C++17, C++20 and C++23 mode by default). After this
patch the modules.exp testsuite finishes in 3m instead of 3m40s with -j8
on my machine.

This patch moves the documentation root URL infix for release branches
from get_option_url/make_doc_url to configure, such that only the default

This commit makes the BPF backend to define the following macros for
c-family languages:
__BPF_CPU_VERSION__
This is a numeric value identifying the version of the BPF "cpu"
for which GCC is generating code.
__BPF_FEATURE_ALU32
__BPF_FEATURE_JMP32
__BPF_FEATURE_JMP_EXT
__BPF_FEATURE_BSWAP
__BPF_FEATURE_SDIV_SMOD
__BPF_FEATURE_MOVSX
__BPF_FEATURE_LDSX
__BPF_FEATURE_GOTOL
__BPF_FEATURE_ST
These are defines if the corresponding "feature" is enabled. The
features are implicitly enabled by the BPF CPU version enabled,
and most of them can also be enabled/disabled using
target-specific -m[no-]FEATURE command line switches.
Note that this patch moves the definition of bpf_target_macros, that
implements TARGET_CPU_CPP_BUILTINS in the BPF backend, to a bpf-c.cc
file. This is because we are now using facilities from c-family/* and
these features are not available in compilers like lto1.
A couple of tests are also added.
Tested in target bpf-unknown-none-gcc and host x86_64-linux-gnu.
No regressions.

When merging an imported function template specialization with an
existing one, if the existing one has an undeduced return type and the
imported one's is already deduced, we need to propagate the deduced type
since once we install the imported definition we won't get a chance to
deduce it by normal means.
So this patch makes is_matching_decl propagate the deduced return
type alongside our propagation of the exception specification.
Another option would be to propagate it later when installing the
imported definition from read_function_def, but it seems preferable
to do it sooner rather than later.

The following testcase is rejected with
error: inlining failed in call to 'always_inline' '...': call is unlikely and code size would grow
errors. The problem is that starting with the r14-2149 change
we try to copy most of the attributes from the inherited to
inheriting ctor, but don't copy associated flags that decl_attributes
sets.
Now, the other clone_attrs user, cp/optimize.cc (maybe_clone_body)
copies over
DECL_COMDAT (clone) = DECL_COMDAT (fn);
DECL_WEAK (clone) = DECL_WEAK (fn);
if (DECL_ONE_ONLY (fn))
cgraph_node::get_create (clone)->set_comdat_group (cxx_comdat_group (clone));
DECL_USE_TEMPLATE (clone) = DECL_USE_TEMPLATE (fn);
DECL_EXTERNAL (clone) = DECL_EXTERNAL (fn);
DECL_INTERFACE_KNOWN (clone) = DECL_INTERFACE_KNOWN (fn);
DECL_NOT_REALLY_EXTERN (clone) = DECL_NOT_REALLY_EXTERN (fn);
DECL_VISIBILITY (clone) = DECL_VISIBILITY (fn);
DECL_VISIBILITY_SPECIFIED (clone) = DECL_VISIBILITY_SPECIFIED (fn);
DECL_DLLIMPORT_P (clone) = DECL_DLLIMPORT_P (fn);
DECL_DISREGARD_INLINE_LIMITS (clone) = DECL_DISREGARD_INLINE_LIMITS (fn);
The following patch just copies DECL_DISREGARD_INLINE_LIMITS to fix
this exact bug, not really sure which other flags should be copied
and which shouldn't.
Plus there are tons of other flags, some of which might need to be copied
too, some of which might not, perhaps in both places, like:
DECL_UNINLINABLE, maybe DECL_PRESERVE_P, TREE_USED, maybe
DECL_USER_ALIGN/DECL_ALIGN, maybe DECL_WEAK, maybe
DECL_NO_INSTRUMENT_FUNCTION_ENTRY_EXIT, DECL_NO_LIMIT_STACK.
TREE_READONLY, DECL_PURE_P, TREE_THIS_VOLATILE (for const, pure and
noreturn attributes) probably makes no sense, DECL_IS_RETURNS_TWICE neither
(returns_twice ctor?). What about TREE_NOTHROW?
DECL_FUNCTION_SPECIFIC_OPTIMIZATION, DECL_FUNCTION_SPECIFIC_TARGET...
Anyway, another problem is that if inherited_ctor is a TEMPLATE_DECL, as
also can be seen in the using D<T>::D; case in the testcase, then
DECL_ATTRIBUTES (fn) = clone_attrs (DECL_ATTRIBUTES (inherited_ctor));
attempts to copy the attributes from the TEMPLATE_DECL which doesn't have
them. The following patch copies them from STRIP_TEMPLATE (inherited_ctor)
which does. E.g. DECL_DECLARED_CONSTEXPR_P works fine as the macro
itself uses STRIP_TEMPLATE too, but not 100% sure about other macros used
on inherited_ctor earlier.
