5bc71c2a6b x86-64: Add R_X86_64_CODE_6_GOTTPOFF
For

	add	%reg1, name@gottpoff(%rip), %reg2

and

	add	name@gottpoff(%rip), %reg1, %reg2

add

 #define R_X86_64_CODE_6_GOTTPOFF		50

if the instruction starts at 6 bytes before the relocation offset.
They are similar to R_X86_64_GOTTPOFF.  Linker can covert GOTTPOFF to

	add	$name@tpoff, %reg1, %reg2

Rewrite fx_tcbit, fx_tcbit2 and fx_tcbit3 usage to generate
R_X86_64_GOTPCRELX, R_X86_64_REX_GOTPCRELX, R_X86_64_CODE_4_GOTPCRELX,
R_X86_64_CODE_4_GOTTPOFF, R_X86_64_CODE_4_GOTPC32_TLSDESC and
R_X86_64_CODE_6_GOTTPOFF.

NB: There is no need to check BFD_RELOC_X86_64_CODE_4_GOTTPOFF in
md_assemble since there is only BFD_RELOC_X86_64_GOTTPOFF at this
stage, which will be converted to BFD_RELOC_X86_64_CODE_4_GOTTPOFF
or BFD_RELOC_X86_64_CODE_6_GOTTPOFF in i386_validate_fix.

5 relocations:

 #define R_X86_64_CODE_5_GOTPCRELX		46
 #define R_X86_64_CODE_5_GOTTPOFF		47
 #define R_X86_64_CODE_5_GOTPC32_TLSDESC	48
 #define R_X86_64_CODE_6_GOTPCRELX		49
 #define R_X86_64_CODE_6_GOTPC32_TLSDESC	51

are added for completeness and they are unused.

fd67aa1129 Update year range in copyright notice of binutils files
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.

d87bef3a7b Update year range in copyright notice of binutils files
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.

a2c5833233 Update year range in copyright notice of binutils files
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.
