d95ba7227e RISC-V: Add vector permutation instructions for T-Head VECTOR vendor extension
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 permutation instructions for the "XTheadVector"
extension. The 'th' prefix and the "XTheadVector" extension
are documented in a PR for the RISC-V toolchain conventions ([1]).

86fbfedd71 RISC-V: Add T-Head VECTOR vendor extension.
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.

e5d6f72eb3 bpf: avoid creating wrong symbols while parsing
To support the "pseudo-C" asm dialect in BPF, the BPF parser must often
attempt multiple different templates for a single instruction. In some
cases this can cause the parser to incorrectly parse part of the
instruction opcode as an expression, which leads to the creation of a
new undefined symbol.

Once the parser recognizes the error, the expression is discarded and it
tries again with a new instruction template. However, symbols created
during the process are added to the symbol table and are not removed
even if the expression is discarded.

This is a problem for BPF: generally the assembled object will be loaded
directly to the Linux kernel, without being linked. These erroneous
parser-created symbols are rejected by the kernel BPF loader, and the
entire object is refused.

This patch remedies the issue by tentatively creating symbols while
parsing instruction operands, and storing them in a temporary list
rather than immediately inserting them into the symbol table. Later,
after the parser is sure that it has correctly parsed the instruction,
those symbols are committed to the real symbol table.

This approach is modeled directly after Jan Beulich's patch for RISC-V:

  commit 7a29ee290307087e1749ce610207e93a15d0b78d
  RISC-V: adjust logic to avoid register name symbols

Many thanks to Jan for recognizing the problem as similar, and pointing
me to that patch.

simple macro when building non-ELF targets.

one exception. By adjusting that, the otherwise bogusly named variable
can also be confined to just ELF builds.

(The mnemonic suffix describes the source operand, not the destination

Note that check_{word,long}_reg() do not (currently) appear to require
similar amending, as there are no insn templates permitting an L or W

neither Reg16 nor Reg32.

88bbac7c76 Regenerate gas/config.in and ld/configure
commit d173146d9 "MIPS: Change all E_MIPS_* to EF_MIPS_*"
changed gas/config.in to rename USE_E_MIPS_ABI_O32 to USE_EF_MIPS_ABI_O32
this new name sorts differently when regenerating gas/config.in

commit e922d1eaa "Add ability to change linker warning messages into
errors when reporting executable stacks and/or executable segments."
Introduced two new help strings for --enable-error-execstack and
--enable-error-rwx-segments in configure.ac which weren't included
in ld/configure when regenerated.

	* gas/config.in: Regenerate.
	* ld/configure: Likewise.

f11f256f56 aarch64: Fix error in THE system register checking
The erroneous omission of a "reg_value == " in the THE system register
encoding check added in [1] led to an error which was not picked up in
GCC but which was flagged in Clang due to its use of
[-Werror,-Wconstant-logical-operand] check.  Together with this fix we
add a new test for the THE registers to pick up their illegal use,
adding an extra and important layer of validation.

Furthermore, in separating system register from instruction
implementation (with which only the former was of concern in the cited
patch), additions made to `aarch64-tbl.h' are rolled back so
that these can be added later when adding THE instructions to the
codebase, a more natural place for these changes.

e7d7487987 x86: rework UWRMSR operand swapping

706ce98422 x86: do away with is_evex_encoding()
As we have grown more uses of it, it becomes increasingly more desirable
to replace it by a simpler check. Have i386-gen do at build time what so
far was done at runtime: Deal with templates indicating EVEX-encoding by
other than the EVex attribute, and set that to "dynamic" in such cases.

This then allows simplifying a number of other conditionals as well.

a5e91879d1 x86: split insn templates' CPU field
Right now the opcode table has entries with ISA restrictions of the form
FEAT1|FEAT2, the meaning of which depends on context and requires
special treatment in tc-i386.c: Sometimes this means "both features
requires", whereas originally it was intended to solely mean "all of
these features required". Split the field, with the original one
regaining its original meaning. The new field now truly means "any of
these". The combination of both fields is still and &&-type check, i.e.
(all of these) && (any of these). In the opcode table more involved
combinations of features then also need expressing this way: "all"
entities first, follow by "any" entities enclosed in parentheses, e.g.
x64&(AVX|AVX512F). If the "all" part is empty, parentheses may not be
added around the "any" part (unless parsing logic was further relaxed).

Note that this way AVX512VL no longer needs as much special treatment,
and hence templates previously using AVX512F|AVX512VL are switched to
just AVX512VL.

Note further that this requires FMA handling as resulting from
da0784f961d8 ("x86: fold FMA VEX and EVEX templates") to be slightly
re-done: FMA now becomes more similar to AVX and AVX2.

3e624fa4b8 x86: Cpu64 handling improvements
First of all we want to also accumulate its reverse dependencies, such
that we can use them in cpu_flags_match(). This is in particular in
preparation of APX additions, such that e.g. BMI VEX-encoding templates
can become combined VEX/EVEX ones.

Once we have the reverse dependencies, we can further leverage them to
omit explicit "&x64" from any insn templates dealing with 64-bit-mode-
only ISA extensions. Besides helping readability for several insn
templates we already have, this will also help with what is going to be
added for APX (as all of the new templates would otherwise need to have
"&x64").

Note that rather than leaving a meaningless CPU_64_FLAGS (which is
unused anyway), its emitting is now also suppressed.
