dwarf: Dump .debug_loclists only for DWARF-5
.debug_loclists section is loaded into debug_information as DWARF-5 debug
info and .debug_loc section is loaded into debug_information as pre-DWARF-5
debug info. When dumping .debug_loc section, we should only process
pre-DWARF-5 debug info in debug_information. When dumping .debug_loclists
section, we should only process DWARF-5 info in debug_information.

This puts back %F into translated fatal error messages (and reverts a
few other small changes), to not disturb translation work done for the
2.44 branch.

gdb/compile: add missing entry in bfd_link_callbacks array
clang 19 fails to build gdb with this error:
/home/simark/src/binutils-gdb/gdb/compile/compile-object-load.c:302:3: error: cannot initialize a member subobject of type 'void (*)(const char *, ...) __attribute__((noreturn))' with an lvalue of type 'void (const char *, ...)'
302 | link_callbacks_einfo, /* einfo */
| ^~~~~~~~~~~~~~~~~~~~
This illustrates that the bfd_link_callbacks array is missing an entry
for the "fatal" callback, add it.
The fatal field was added very recently, in d26161914 ("PR 32603, more
ld -w misbehaviour"). We're lucky that the new callback was marked with
the noreturn attribute and that clang checks that, otherwise this would
have gone unnoticed.

PR 32603, more ld -w misbehaviour
Commit 8d97c1a53f3d claimed to replace all einfo calls using %F with
a call to fatal. It did so only for the ld/ directory. This patch
adds a "fatal" to linker callbacks, and replaces those calls in bfd/
too.

PR 32603, ld -w misbehaviour
ld -w currently causes segmentation faults and other misbehaviour
since it changes einfo with %F in the format string (fatal error) to
not exit. This patch fixes that by introducing a new variant of einfo
called "fatal" that always exits, and replaces all einfo calls using
%F with a call to fatal without the %F. I considered modifying einfo
to inspect the first 2 or 4 chars in the format string, looking for
%F, but decided that was probably a bad idea given that translators
might have moved the %F. It's also a little nicer to inform the
compiler of a function that doesn't return.
The patch also fixes some formatting nits, and makes use of %pA
to print section names in a couple of places in aix.em.

x86: Remove AVX10.2 256 bit rounding support
Since we will support 512 bit on both P-core and E-core for AVX10, 256 bit
rounding is not that useful because we currently have rounding feature
directly on E-core now and no need to use 256-bit rounding as somehow
a workaround. This patch will remove all the support and backport to
Binutils 2.44.

gas: fix rs_fill_nop listing
In commit a0094f1a70e1 ("gas: make .nops output visible in listing") I
was wrongly assuming fr_fix would be zero for rs_fill_nop, when that's
only a side effect of listing_newline() inserting dummy frags, but only
when file/line did actually change from the previous invocation. This is
in particular not going to be true when the .nops directive isn't the
first statement on a line.
