Also expand GC interface with "allocate_pointerless". Limit lazy
sweeping to the allocation size that is causing the sweep, without
adding to fragmentation.
Fixes synchronization issues observed on slow or loaded machines, where
client connection attempts would fail with ECONNREFUSED:

* test-suite/tests/web-server.test ("server is listening"): New test.
Before the change ./configure incorrectly enabled -flto on toolchains
that support -flto on compiler side but don't support -flto on linker
side. This caused incorrect type size detection on nixpkgs' Darwin:
configure:54594: checking size of size_t
configure:54600: clang -std=gnu11 -o conftest -g -O2 -flto conftest.c >&5
ld: warning: ignoring file /private/tmp/nix-build-guile-3.0.8.drv-0/conftest-00e93d.o,

Taken from https://github.com/NixOS/nixpkgs/pull/160051#issuecomment-1046105041
The change makes sure -flto support tests basic support of just for
object file generation but for linker as well.
* configure.ac: use AC_LINK_IFELSE instead of AC_COMPILE_IFELSE.

Commit 54bbe0b284 inadvertently led
psyntax to dismiss source location info for data returned by read hash
extensions, because read hash extensions return plain data with
associated source properties, even when called from 'read-syntax'.
This change reverts part of this commit to restore that behavior.
Fixes <https://issues.guix.gnu.org/54003>.
* module/ice-9/psyntax.scm (datum-sourcev): New procedure.
(source-annotation): Fall back to 'datum-sourcev'.
* module/ice-9/psyntax-pp.scm: Regenerate.
* test-suite/tests/compiler.test ("psyntax")["syntax-source with
read-hash-extend"]: New test.
Fixes <https://issues.guix.gnu.org/54198>.
As noted in the comment at the top, 'SIZEOF_TYPE' must be used instead
of 'sizeof (TYPE)' to support cross-compilation.
The regression was introduced in
5e5afde06f but only became apparent with
717e787da6.
* libguile/gen-scmconfig.c (main): Replace uses of 'sizeof' by
references to the SIZEOF_* macros.
* configure.ac: Add 'AC_CHECK_SIZEOF' call for 'intmax_t'.
Avoiding systematic conversion from source vectors to property alists
saves 20% on the final heap size of a process doing:
(compile-file FILE #:optimization-level 1)
where FILE is large.
* module/language/tree-il.scm (tree-il-src/ensure-alist): New procedure
with setter. Export as 'tree-il-src'.
* module/ice-9/psyntax.scm (build-void, build-call)
(build-conditional, build-lexical-reference, build-lexical-assignment)
(build-global-reference, build-global-assignment)
(build-global-definition, build-simple-lambda, build-case-lambda)
(build-lambda-case, build-primcall, build-primref)
(build-data, build-sequence, build-let, build-named-let)
(build-letrec, expand-body): Remove (sourcev->alist src) calls.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/language/tree-il/analyze.scm (shadowed-toplevel-analysis): Use
'tree-il-src' instead of accessing the 'src' slot directly.
* module/system/vm/assembler.scm (link-debug): Adjust so PC can be
followed by a vector or an alist.
* libguile/srfi-14.i.c: Update from Unicode 14.0.0.
* libguile/unidata_to_charset.pl (compute): Write arrays as static const
data, to avoid polluting the namespace and to avoid adding these to the
GC root set.
* libguile/srfi-14.c (SCM_CODEPOINT_F_IMMUTABLE): New flag.
(scm_charset_is_immutable): New internal predicate.
(SCM_VALIDATE_MUTABLE_CHARSET): New internal validator.
(cs_full_ranges, cs_full_ranges_len): Re-express as separate ranges and
len, because the ranges pointer in scm_t_char_set is mutable.
(scm_char_set_unfold_x, scm_list_to_char_set_x)
(scm_string_to_char_set_x, scm_char_set_filter_x)

(scm_char_set_unfold_x, scm_char_set_intersection_x)
(scm_char_set_difference_x, scm_char_set_xor_x): Require mutable
charsets.
(define_charset): Add immutable flag.
(scm_init_srfi_14): Adapt initial charset definitions.
