bb-slp-40.c fails on SPARC targets without VIS4 because it
requires addition on vectors of bytes. There doesn't seem to be
an existing target selector for this, so I added vect_char_add.
(Wasn't sure whether to use vect_char_add, for consistency
with vect_no_int_add/vect_int_mult etc., or vect_add_char for
consistency with vect_shift_char etc.)
I took the target list from vect_int and removed targets that didn't
seem to support the operation (namely sparc*, since we don't seem to
have any test for VIS4, niagara7 or m8, and alpha*-*-*.)

The FTP protocol is getting long in the tooth, and we should emphasize
HTTPS where that is available. This patch changes various gcc.gnu.org
URL's to instead use HTTPS.
For instance, kernel.org shut down FTP access in 2017, with the
explanation:
- The protocol is inefficient and requires adding awkward kludges to
firewalls and load-balancing daemons
- FTP servers have no support for caching or accelerators, which has
significant performance impacts
- Most software implementations have stagnated and see infrequent
updates

Since r278084 (part of the params refactoring), most of libgccjit's
test suite has been ICEing.
The root cause is that jit-playback.c injects params to its fake_args
here:
/* Aggressively garbage-collect, to shake out bugs: */
if (get_bool_option (GCC_JIT_BOOL_OPTION_SELFCHECK_GC))
{
ADD_ARG ("--param");
ADD_ARG ("ggc-min-expand=0");
ADD_ARG ("--param");
ADD_ARG ("ggc-min-heapsize=0");
}
(building a vec of char * where the char * are allocated using xstrdup)
and r278084 added this logic to decode_cmdline_options_to_array:
964 /* Interpret "--param" "key=name" as "--param=key=name". */
965 const char *needle = "--param";
966 if (i + 1 < argc && strcmp (opt, needle) == 0)
967 {
968 const char *replacement
969 = opts_concat (needle, "=", argv[i + 1], NULL);
970 argv[++i] = replacement;
971 }
Note that at line 970 it manipulates the argv in-place, inserting a
new option allocated with opts_concat, which uses opts_obstack
(itself initialized from toplev::main).
jit-playback.c cleans up its fake arguments using "free", at which
point we have a free of the middle of an obstack and an ICE.
This patch fixes the issue by using the new syntax for the params.
Fixes all 60 FAILs in jit.sum, restoring the number of PASS results
from 2033 to 10469.

GCC currently defaults to -fcommon. As discussed in the PR, this is an ancient
C feature which is not conforming with the latest C standards. On many targets
this means global variable accesses have a codesize and performance penalty.

time to change the default.

The standard [[]] attributes currently defined in C2x are all not
valid on types not being defined at the time.
Use on such types results in a warning from attribs.c about attributes
appertaining to types (the warning that I think is bogus in general
for both C and C++, applying as it does to all [[]] attributes
including gnu:: ones that are perfectly meaningful on types not being
defined and work fine when __attribute__ syntax is used instead). If
that warning is removed (as I intend to do in a subsequent patch),
warnings may or may not result from the attribute handlers, depending
on whether those particular attribute handlers consider the attributes
meaningful in such a context. In C, however, the rules about where
each [[]] attribute is valid are constraints, so a pedwarn, not a
warning, is required.
Because some handlers are shared between standard and gnu::
attributes, there can be cases that are valid for the GNU attribute
variant but not for the standard one. So in general it is not correct
to rely on the attribute handlers to give all required pedwarns
(although in some cases, a pedwarn in the attribute handler is in
appropriate way of diagnosing an invalid use); they not have the
information about whether the attribute was a gnu:: one and can
legitimately accept a wider range of uses for the gnu:: attributes.
This patch ensures appropriate diagnostics for invalid uses of C2x
standard attributes on types, and so helps pave the way for the
subsequent removal of the bogus check in attribs.c, by adding a check
run in the front end before calling decl_attributes; this check
removes the attributes from the list after calling pedwarn to avoid
subsequent duplicate warnings.

The C++ committee continues to discuss how best to avoid breaking existing

base the tie-breaker on the parameter types of the candidates, which made a
lot of sense to me, so this patch implements that.

printing the list of candidates, and warns about a comparison that becomes
