This adds support of new instructions to the S/390 specific parts.
The important feature of the new instruction set is the support of
single and extended precision floating point vector operations.
Note: arch12 is NOT the official name of the new CPU. It just
continues the series of archXX options supported as alternate names.
The archXX terminology refers to the edition number of the Principle
of Operations manual. The official CPU name will be added later while
keeping support of the arch12 for backwards compatibility.
No testsuite regressions.
Committed to mainline.

Identify non-extensible instructions in the MIPS16 opcode table and
disallow their use with the `.e' instruction size suffix in assembly and
do not interpret any EXTEND prefix present as a part of the instruction
in disassembly.
According to all versions of the MIPS16 ASE specifications the following
instructions encodings are not extensible [1][2][3][4][5][6]: I8/MOV32R,
I8/MOVR32, all RRR minor opcodes, all RR minor opcodes except from DSRA
and DSRL, and EXTEND itself, and as from revision 2.50 of the MIPS16e
ASE specifications it has been further clarified what was previously
implied, that non-extesiable instructions when preceded with an EXTEND
prefix must cause a Reserved Instruction exception [3][5].
Therefore in the presence of an EXTEND prefix none of these instructions
are supposed to be handled as extended instructions and supporting these
forms in disassembly causes confusion, and in the case of the RRR major
opcode it also clashes with the ASMACRO encoding.

Switch to 32-bit MIPS16 opcode table entry interpretation, similar to
how the microMIPS opcode table is handled, for both the `match' and
`mask' fields, removing special casing for JAL and JALX instructions and
their `a' and `i' operand codes throughout, while retaining automatic
processing of extendable opcodes in assembly and disassembly.
In assembly disallow size enforcement suffixes as appropriate: `.t' for
both 32-bit instructions and macros and `.e' for macros only, making
macro handling consistent with the microMIPS instruction set.
In disassembly fully decode EXTEND prefixes prepended to unsupported
instruction encodings (according to the ISA selection) rather than
dumping them as hexadecimal data along with the following instruction,
removing all special casing for the EXTEND prefix and making its
handling rely on its opcode table entry, except where it is considered a
part of an extendable instruction.

When the assembler finds an instruction which is part of a higher
opcode architecture it bumps the current opcode architecture. For
example:
$ echo "mwait" | as -bump
{standard input}: Assembler messages:
{standard input}:1: Warning: architecture bumped from "v6" to "v9m" on "mwait"
However, when two instructions pertaining to the same opcode
architecture but associated to different SPARC hardware capabilities
are found in the input stream, and no GAS architecture is specified in
the command line, the assembler bangs:
$ echo "mwait; wr %g0,%g1,%mcdper" | as -bump
{standard input}: Assembler messages:
{standard input}:1: Warning: architecture bumped from "v6" to "v9m" on "mwait"
{standard input}:1: Error: Hardware capability "sparc5" not enabled for "wr".
... and it should'nt, as WRMCDPER pertains to the same architecture
level than MWAIT.
This patch fixes this by extending the definition of sparc opcode
architectures to contain a set of hardware capabilities and making the
assembler to take these capabilities into account when updating the
set of allowed hwcaps when an architecture bump is triggered by some
instruction.
This way, hwcaps associated to architecture levels are maintained in
opcodes, while the assembler keeps the flexibiity of defining GAS
architectures including additional hwcaps (like -Asparcfmaf or the
v8plus* variants).
A test covering this failure case is included.

The current handling for arc instructions longer than 32-bits is all
handled as a special case in both the assembler and disassembler.
The problem with this approach is that it leads to code duplication,
selecting a long instruction is exactly the same process as selecting a
short instruction, except over more bits, in both cases we select based
on bit comparison, and initial operand insertion and extraction.
This commit unifies both the long and short instruction worlds,
converting the core opcodes library from being largely 32-bit focused,
to being largely 64-bit focused.
The changes are, on the whole, not too much. There's obviously a lot of
type changes but otherwise the bulk of the code just works. Most of the
actual functional changes are to code that previously handled the longer
48 or 64 bit instructions. The insert/extract handlers for these have
now been brought into line with the short instruction insert/extract
handlers.
All of the special case handling code that was previously added has now
been removed again. Overall, this commit reduces the amount of code in
the arc assembler and disassembler.

The ARC (short) instructions are using a special register number to
indicate is the instruction uses a long immediate (LIMM). In the case
of short instruction, this LIMM indicator depends on the ISA version
used. Thus, for ARCv1 processors, the LIMM indicator is 0x3E, the same
value used in "long" instructions. However, for the ARCv2 processors,
this LIMM indicator is 0x1E.
This patch fixes the LIMM detection for ARCv1 ISA and adds two tests.

SVE defines new names for existing NZCV conditions, to reflect the
result of instructions like PTEST. This patch adds support for these
names.
The patch also adds comments to the disassembly output to show the
alternative names of a condition code. For example:
cinv x0, x1, cc
becomes:
cinv x0, x1, cc // cc = lo, ul, last
and:
b.cc f0 <...>
becomes:
b.cc f0 <...> // b.lo, b.ul, b.last
Doing this for the SVE names follows the practice recommended by the
SVE specification and is definitely useful when reading SVE code.
If the feeling is that it's too distracting elsewhere, we could add
an option to turn it off.

This patch adds support for the new SVE floating-point immediate
operands. One operand uses the same 8-bit encoding as base AArch64,
but in a different position. The others use a single bit to select
between two values.
One of the single-bit operands is a choice between 0 and 1, where 0
is not a valid 8-bit encoding. I think the cleanest way of handling
these single-bit immediates is therefore to use the IEEE float encoding
itself as the immediate value and select between the two possible values
when encoding and decoding.
As described in the covering note for the patch that added F_STRICT,
we get better error messages by accepting unsuffixed vector registers
and leaving the qualifier matching code to report an error. This means
that we carry on parsing the other operands, and so can try to parse FP
immediates for invalid instructions like:
fcpy z0, #2.5
In this case there is no suffix to tell us whether the immediate should
be treated as single or double precision. Again, we get better error
messages by picking one (arbitrary) immediate size and reporting an error
for the missing suffix later.

This patch adds the new SVE integer immediate operands. There are
three kinds:
- simple signed and unsigned ranges, but with new widths and positions.
- 13-bit logical immediates. These have the same form as in base AArch64,
but at a different bit position.
In the case of the "MOV Zn.<T>, #<limm>" alias of DUPM, the logical
immediate <limm> is not allowed to be a valid DUP immediate, since DUP
is preferred over DUPM for constants that both instructions can handle.
- a new 9-bit arithmetic immediate, of the form "<imm8>{, LSL #8}".
In some contexts the operand is signed and in others it's unsigned.
As an extension, we allow shifted immediates to be written as a single
integer, e.g. "#256" is equivalent to "#1, LSL #8". We also use the
shiftless form as the preferred disassembly, except for the special
case of "#0, LSL #8" (a redundant encoding of 0).

This patch adds support for addresses of the form:
[<base>, #<offset>, MUL VL]
This involves adding a new AARCH64_MOD_MUL_VL modifier, which is
why I split it out from the other addressing modes.
For LD2, LD3 and LD4, the offset must be a multiple of the structure
size, so for LD3 the possible values are 0, 3, 6, .... The patch
therefore extends value_aligned_p to handle non-power-of-2 alignments.

This patch adds most of the new SVE addressing modes and associated
operands. A follow-on patch adds MUL VL, since handling it separately
makes the changes easier to read.
The patch also introduces a new "operand-dependent data" field to the
operand flags, based closely on the existing one for opcode flags.
For SVE this new field needs only 2 bits, but it could be widened
in future if necessary.

Some SVE instructions count the number of elements in a given vector
pattern and allow a scale factor of [1, 16] to be applied to the result.
This scale factor is written ", MUL #n", where "MUL" is a new operator.
E.g.:
UQINCD X0, POW2, MUL #2
This patch adds support for this kind of operand.
All existing operators were shifts of some kind, so there was a natural
range of [0, 63] regardless of context. This was then narrowered further
by later checks (e.g. to [0, 31] when used for 32-bit values).
In contrast, MUL doesn't really have a natural context-independent range.
Rather than pick one arbitrarily, it seemed better to make the "shift"
amount a full 64-bit value and leave the range test to the usual
operand-checking code. I've rearranged the fields of aarch64_opnd_info
so that this doesn't increase the size of the structure (although I don't
think its size is critical anyway).
