This patch adds support for generating unlabeled landing pad PLT entries
for the RISC-V architecture. Unlabeled landing pad will place a LPAD
instruction at the PLT entry and PLT header, also PLT header will have
few changes due to the offset is different from the original one.

T-Head has a range of vendor-specific instructions. Therefore
it makes sense to group them into smaller chunks in form of
vendor extensions.
This patch adds the additional extension "XTheadVdot" based on the
"V" extension, and it provides four 8-bit multiply and add with
32-bit instructions for the "v" extension. The 'th' prefix and the
"XTheadVector" extension are documented in a PR for the
RISC-V toolchain conventions ([2]).

The privileged spec v1.10 already removed the sfence.vm instruction, and the
encoding of sfence.vm instruction is overlapped with the sctrclr instruction
of ssctr/smctr. But since the privileged spec v1.10 already removed the
sfence.vm, and we no longer support the privileged spec v1.9.1 for now, we
had to remove the sfence.vm.

check the 'zcmt_index' field to distinguish them.

This implements the Zvfbfwma extension, as of version 1.0.

1 In spec: "Zvfbfwma requires the Zvfbfmin extension and the Zfbfmin extension."
1.1 In Embedded Processor: Zvfbfwma -> Zvfbfmin -> Zve32f
1.2 In Application Processor: Zvfbfwma -> Zvfbfmin -> V
1.3 In both scenarios, there are: Zvfbfwma -> Zfbfmin
2 Depending on different usage scenarios, the Zvfbfwma extension may
depend on 'V' or 'Zve32f'. This patch only implements dependencies in
scenario of Embedded Processor. This is consistent with the processing
strategy in Zvfbfmin. In scenario of Application Processor, it is
necessary to explicitly indicate the dependent 'V' extension.

1 The Zfbfmin extension depend on 'F', and the FLH, FSH, FMV.X.H, and
FMV.H.X instructions as defined in the Zfh extension.
2 The Zfhmin extension includes the following instructions from the Zfh
extension: FLH, FSH, FMV.X.H, FMV.H.X... View detailed information in:
<https://github.com/riscv/riscv-isa-manual/blob/main/src/zfh.adoc>
3 Zfhmin extension depend on 'F'.
4 Simply put, just make Zfbfmin dependent on Zfhmin.
Perhaps in the future, we could propose making the FLH, FSH, FMV.X.H, and
FMV.H.X instructions an independent extension to achieve precise dependency
relationships for the Zfbfmin.

Since the particularity of "th.vsetvli" was not taken into account in the
initial support patches for XTheadVector, the program operation failed
due to instruction coding errors. According to T-Head SPEC ([1]), the
"vsetvl" in the XTheadVector extension consists of SEW, LMUL and EDIV,
which is quite different from the "V" extension. Therefore, we cannot
simply reuse the processing of vsetvl in V extension.
We have set up tens of thousands of test cases to ensure that no
further encoding issues are there, and and execute all compiled test
files on real HW and make sure they don't trigger SIGILL.

Back then when the support for the RISC-V vector crypto extensions
was merged, the specification was frozen, but not ratified.
A frozen specification is allowed to change within tight bounds
before ratification and this has happend with the vector crypto
extensions.
The following changes were applied:
* A new extension Zvkb was defined, which is a strict subset of Zvbb.
* Zvkn and Zvks include now Zvkb instead of Zvbb.
This patch implements these changes between the frozen and the
ratified specification.
Note, that this technically an incompatible change of Zvkn and Zvks,
but I am not aware of any project that depends on the currently
implemented behaviour of Zvkn and Zvks. So this patch should be fine.

T-Head has a range of vendor-specific instructions. Therefore
it makes sense to group them into smaller chunks in form of
vendor extensions.
This patch adds the sub-extension "XTheadZvamo" for the
"XTheadVector" extension, and it provides AMO instructions
for T-Head VECTOR vendor extension. The 'th' prefix and the
"XTheadVector" extension are documented in a PR for the
RISC-V toolchain conventions ([1]).

T-Head has a range of vendor-specific instructions ([2]).
Therefore it makes sense to group them into smaller chunks
in form of vendor extensions.
This patch adds the "XTheadVector" extension, a collection of
T-Head-specific vector instructions. The 'th' prefix and the
"XTheadVector" extension are documented in a PR for the RISC-V
toolchain conventions ([1]).
Here are some things that need to be explained:
The "XTheadVector" extension is not a custom-extension, but
a non-standard non-conforming extension. The encoding space
of the "TheadVector" instructions overlaps with those of
the 'V' extension. This encoding space conflict is not on
purpose, but the result of issues in the past that have
been resolved since. Therefore, the "XTheadVector" extension
and the 'V' extension are in conflict.

Within the groups L{B,BU,H,HU,W,WU,D}, S{B,H,W,D}, FL{H,W,D,Q}, and
FS{H,W,D,Q} the sole difference between the handling is the insn
mnemonic passed to the common handling functions. The intended mnemonic,
however, can easily be retrieved. Furthermore leverags that Sx and FSx
are then handled identically, too, and hence their cases can also be
folded.
There's no need to have almost identical code twice. Do away with
M_VMSGEU and instead simply use an unused (for these macros) field to
tell apart both variants.
The documentation of the 'Zfa' extension states that "fli.h" is available
"if the Zfh or Zvfh extension is implemented" (both the latest and the
oldest editions are checked).
This fact was not reflected in Binutils ('Zvfh' implies 'Zfhmin', not full
'Zfh' extension and "fli.h" required 'Zfh' and 'Zfa' extensions).
This commit makes "fli.h" also available when both 'Zfa' and 'Zvfh'

The longest register name is 4 characters (plus a nul one), so using a
4- or 8-byte pointer to get at it is neither space nor time efficient.
Embed the names right into the array. For PIE this also reduces the
number of base relocations in the final image.
To avoid old gcc, when generating 32-bit code, bogusly warning about
bounds being exceeded in the code processing Cs/Cw, Ct/Cx, and CD,
an adjustment to EXTRACT_BITS() is needed: This macro shouldn't supply
a 64-bit value, and it also doesn't need to - all operand fields to
date are far more narrow than 32 bits. This in turn allows dropping a
number of casts elsewhere.
This patch support Zcb extension, contains new compressed instructions,
some instructions depend on other existed extension, like 'zba', 'zbb'
and 'zmmul'. Zcb also imply Zca extension to enable the compressing
features.

Currently we have three instruction classes defined for Zvkh[a,b]:

- INSN_CLASS_ZVKNHB
- INSN_CLASS_ZVKNHA_OR_ZVKNHB
The encodings of all instructions in Zvknh[a,b] are identical.
Therefore, we don't need the individual instruction classes
and can remove them.
This patch also adds the missing support of the combined instruction
class in riscv_multi_subset_supports_ext().
