618655192f [AArch64] Implement branch over stub section.
Ensure that injection of a stub section does not break a link where
there is an xpectation that flow of control can pass from one input
section to another simply by linking the input sections in series.

The solution here is to allow stub sections to be inserted after any
input section (existing behaviour), but inject an additional branch at
the start of each stub section such that control flow falling into the
stub section will branch over the stub section.

d422d1c433 Garbage collecting debug sections
I noticed that _bfd_elf_gc_mark_extra_sections attempts to unmark
related debug sections when it finds an unmarked code section.
When it finds .text.foo is unmarked, for example, it removes
.debug_line.text.foo as well (using the section name as a suffix
match check.

However, it bails out after finding one such section.

2ec55de302 Properly place the NULL STT_FILE symbol revistited
I was having a little closer look at what is going on here and noticed
that HJ unconditionally emits a NULL STT_FILE symbol before emitting
forced local symbols.  That means we really don't need a second pass
over forced local symbols.  The only reason for two passes is when
some forced local symbol can be emitted before the NULL STT_FILE.  So
I set about removing the second pass, updating the testsuite all over
again.  It's also unnecessary to emit the NULL STT_FILE when no
previous file symbol has been emitted.

ce875075f9 PR ld/17973 LTO file syms
LTO output objects have an STT_FILE symbol using the name of the file,
a temporary file.  This results in executables that can't be exactly
reproduced, so the file name needs to be dropped.  We don't want to
lose all file symbols when linking a mix of lto and non-lto objects as
a file symbol can be used to figure which source file generated a
given local symbol.  So lto output objects need to be marked.

I chose to mark lto output objects with a new bfd flag.  This flag is
also used to fix a bug in the link-once handling;  An object being
loaded after "loading_lto_outputs" is set might be one extracted from
an archive to satisfy new references from lto objects, not an lto
object itself.

The new flag is copied from archive to elements, and the same done
for no_export.  This fixes a bug in that --exclude-libs doesn't work
with thin archives.  I'm not completely happy with this part of the
patch and may revist this to avoid the hack in
_bfd_look_for_bfd_in_cache.

5ae0078cd2 Merge linker plugin handling into BFD plugin support
Linker plugin_maybe_claim is the interface of linker plugin support.
This patch extracts linker plugin_maybe_claim into plugin_object_p and
makes it available to BFD via a new function:

void register_ld_plugin_object_p (const bfd_target *(*) (bfd *));

bfd_plugin_object_p calls plugin_object_p registered by linker first.  It
adds an enum bfd_plugin_format field and a pointer to plugin dummy BFD so
that plugin_object_p stores plugin dummy BFD to allow plugin_maybe_claim
to retrieve it later.
