Adds two new external authors to etc/update-copyright.py to cover
bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then
updates copyright messages as follows:
1) Update cgen/utils.scm emitted copyrights.
2) Run "etc/update-copyright.py --this-year" with an extra external
author I haven't committed, 'Kalray SA.', to cover gas testsuite
files (which should have their copyright message removed).
3) Build with --enable-maintainer-mode --enable-cgen-maint=yes.
4) Check out */po/*.pot which we don't update frequently.
The newer update-copyright.py fixes file encoding too, removing cr/lf
on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and
embedded cr in binutils/testsuite/binutils-all/ar.exp string match.
The result of running etc/update-copyright.py --this-year, fixing all
the files whose mode is changed by the script, plus a build with
--enable-maintainer-mode --enable-cgen-maint=yes, then checking
out */po/*.pot which we don't update frequently.
The copy of cgen was with commit d1dd5fcc38ead reverted as that commit
breaks building of bfp opcodes files.
The libiberty hash table includes a helper function for strings, but
no equality function. Consequently, this equality function has been
reimplemented a number of times in both the gcc and binutils-gdb
source trees. This patch adds the function to the libiberty hash
table, as a step toward the goal of removing all the copies.
One change to gcc is included here. Normally I would have put this in
the next patch, but gensupport.c used the most natural name for its
reimplementation of this function, and this can't coexist with the
extern function in libiberty.

This commit pulls in the latest changes for the include/ and
libiberty/ directories. The last sync was in commit
533da48302.
This commit also removes the file libiberty/rust-demangle.h, this file
has been removed in upstream GCC, and should have been deleted as part
of the previous sync up, which included this ChangeLog entry:
2019-11-16 Eduard-Mihai Burtescu <eddyb@lyken.rs>
....
* rust-demangle.h: Remove.
I've grep'd over the binutils-gdb source and can find no reference to
the rust-demangle.h file, and everything seems to build fine without
it, so I assume its continued existence was a mistake.

* simple-object-elf.c (simple_object_elf_copy_lto_debug_section):
Do not use UNDEF locals for removed symbols but instead just
define them in the first prevailing section and with no name.
Use the same gnu_lto_v1 name for all removed globals we promote to
WEAK UNDEFs so hpux can use a stub to provide this symbol. Clear
sh_info and sh_link in removed sections.

Adjust some comments, add some explicit fall through comments or explicit
returns where necessary to not get implicit-fallthrough warnings.
All fall throughs were deliberate. In one case I added an explicit return
false for clarity instead of falling through a default case (that also
would return false).
