Add the MT ASE instruction operand types and encodings to the microMIPS
opcode table and enable the assembly of these instructions in GAS from
MIPSr2 onwards. Update the binutils and GAS testsuites accordingly.

Base and index register 0 have no effect in address computation:
"A value of zero in the B [base] or X [index] field specifies that no
base or index is to be applied, and, thus, general register 0 cannot be
designated as containing a base address or index."
IBM z/Architecture Principles of Operation [1], chapter "Organization",
section "General Registers".
Index register 0 is omitted in the s390 disassembly. Base register 0 is
omitted in D(B), D(L,B) and D(X,B) - the latter only if the index
register is zero.
To make it more apparent print base register 0 as "0" instead of "%r0",
whenever it would still be printed in the disassembly.

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.

Print instruction description as comment in disassembly with s390
architecture specific option "insndesc":
- For objdump it can be enabled with option "-M insndesc"
- In gdb it can be enabled with "set disassembler-options insndesc"
Since comments are not column aligned the output can enhanced for
readability by postprocessing using a filter such as "expand":
... | expand -t 8,16,24,32,40,80
Or when using in combination with objdump option --visualize-jumps:
... | expand | sed -e 's/ *#/\t#/' | expand -t 1,80
Note that the instruction descriptions add about 128 KB to s390-opc.o:
s390-opc.o without instruction descriptions: 216368 bytes
s390-opc.o with instruction descriptions : 348432 bytes

Add support for jump visualization for the s390 architecture in
disassembly:
objdump -d --visualize-jumps ...
Annotate the (conditional) jump and branch relative instructions with
information required for jump visualization:
- jump: Unconditional jump / branch relative.
- condjump: Conditional jump / branch relative.
- jumpsr: Jump / branch relative to subroutine.
Unconditional jump and branch relative instructions are annotated as
jump.
Conditional jump and branch relative instructions, jump / branch
relative on count/index, and compare and jump / branch relative
instructions are annotated as condjump.
Jump and save (jas, jasl) and branch relative and save (bras, brasl)
instructions are annotated as jumpsr (jump to subroutine).
Provide instruction information required for jump visualization during
disassembly.
The instruction type is provided after determining the opcode.
For non-code it is set to dis_noninsn. Otherwise it defaults to
dis_nonbranch. No annotation is done for data reference instructions
(i.e. instruction types dis_dref and dis_dref2). Note that the
instruction type needs to be provided before printing of the
instruction, as it is used in print_address_func() to translate the
argument value into an address if it is assumed to be a PC-relative
offset. Note that this is never the case on s390, as
print_address_func() is only called with addresses and never with
offsets.
The target of the (conditional) jump and branch relative instructions
is provided during print, when the PC relative operand is decoded.
include/
* opcode/s390.h: Define opcode flags to annotate instruction
class information for jump visualization:
S390_INSTR_FLAG_CLASS_BRANCH, S390_INSTR_FLAG_CLASS_RELATIVE,
S390_INSTR_FLAG_CLASS_CONDITIONAL, and
S390_INSTR_FLAG_CLASS_SUBROUTINE.
Define opcode flags mask S390_INSTR_FLAG_CLASS_MASK for above
instruction class information.
Define helpers for common instruction class flag combinations:
S390_INSTR_FLAGS_CLASS_JUMP, S390_INSTR_FLAGS_CLASS_CONDJUMP,
and S390_INSTR_FLAGS_CLASS_JUMPSR.
opcodes/

This commit adds the _option_ of having disassembler output syntax
highlighted in objdump. This option is _off_ by default. The new
command line options are:
--disassembler-color=off # The default.
--disassembler-color=color
--disassembler-color=extended-color
I have implemented two colour modes, using the same option names as we
use of --visualize-jumps, a basic 8-color mode ("color"), and an
extended 8bit color mode ("extended-color").
The syntax highlighting requires that each targets disassembler be
updated; each time the disassembler produces some output we now pass
through an additional parameter indicating what style should be
applied to the text.
As updating all target disassemblers is a large task, the old API is
maintained. And so, a user of the disassembler (i.e. objdump, gdb)
must provide two functions, the current non-styled print function, and
a new, styled print function.
I don't currently have a plan for converting every single target
disassembler, my hope is that interested folk will update the
disassemblers they are interested in. But it is possible some might
never get updated.
In this initial series I intend to convert the RISC-V disassembler
completely, and also do a partial conversion of the x86 disassembler.
Hopefully having the x86 disassembler at least partial converted will
allow more people to try this out easily and provide feedback.
In this commit I have focused on objdump. The changes to GDB at this
point are the bare minimum required to get things compiling, GDB makes
no use of the styling information to provide any colors, that will
come later, if this commit is accepted.
This first commit in the series doesn't convert any target
disassemblers at all (the next two commits will update some targets),
so after this commit, the only color you will see in the disassembler
output, is that produced from objdump itself, e.g. from
objdump_print_addr_with_sym, where we print an address and a symbol
name, these are now printed with styling information, and so will have
colors applied (if the option is on).
Finally, my ability to pick "good" colors is ... well, terrible. I'm
in no way committed to the colors I've picked here, so I encourage
people to suggest new colors, or wait for this commit to land, and
then patch the choice of colors.
I do have an idea about using possibly an environment variable to
allow the objdump colors to be customised, but I haven't done anything
like that in this commit, the color choices are just fixed in the code
for now.

This adds support for efi-*-aarch64 by virtue of adding a new PEI target
pei-aarch64-little. This is not a full target and only exists to support EFI
at this time.
This means that this target does not support relocation processing and is mostly
a container format. This format has been added to elf based aarch64 targets
such that efi images can be made natively on Linux.
However this target is not valid for use with gas but only with objcopy.
With these changes the resulting file is recognized as an efi image by
third party tools:
