Change the default language version for C compilation from -std=gnu17
to -std=gnu23. A few tests are updated to remove local definitions of
bool, true and false (where making such an unconditional test change
seemed to make more sense than changing the test conditionally earlier
or building it with -std=gnu17); most test issues were already
addressed in previous patches. In the case of
ctf-function-pointers-2.c, it was agreed in bug 117289 that it would
be OK to put -std=gnu17 in the test and leave more optimal BTF / CTF
output for this test as a potential future improvement.
Since the original test fixes, more such fixes have become necessary
and so are included in this patch. More noinline attributes are added
to simulate-thread tests where () meaning a prototype affected test
results, while gcc.dg/torture/pr117496-1.c (a test declaring a
function with () then calling it with arguments) gets -std=gnu17
added.
Bootstrapped with no regressions for x86_64-pc-linux-gnu.
NOTE: it's likely there are target-specific tests for non-x86 targets
that need updating as a result of this change. See commit

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
