[binutils][aarch64] SVE2 feature extension flags.
Include all feature flag macros.
The "sve2" extension that enables the core sve2 instructions.
This also enables the sve extension, since sve is a requirement of sve2.
Extra optional sve2 features are the bitperm, sm4, aes, and sha3 extensions.
These are all given extra feature flags, "bitperm", "sve2-sm4",
"sve2-aes", and "sve2-sha3" respectively.
The sm4, aes, and sha3 extensions are explicitly marked as sve2
extensions to distinguish them from the corresponding NEON extensions.
Rather than continue extending the current feature flag numbers, I used
some bits that have been skipped.

[BINUTILS, AArch64, 2/2] Update Store Allocation Tag instructions
This patch updates the Store allocation tags instructions in
Armv8.5-A Memory Tagging Extension. This is part of the changes
that have been introduced recently in the 00bet10 release
All of these instructions have an updated register operand (Xt -> <Xt|SP>)
- STG <Xt|SP>, [<Xn|SP>, #<simm>]
- STG <Xt|SP>, [<Xn|SP>, #<simm>]!
- STG <Xt|SP>, [<Xn|SP>], #<simm>
- STZG <Xt|SP>, [<Xn|SP>, #<simm>]
- STZG <Xt|SP>, [<Xn|SP>, #<simm>]!
- STZG <Xt|SP>, [<Xn|SP>], #<simm>
- ST2G <Xt|SP>, [<Xn|SP>, #<simm>]
- ST2G <Xt|SP>, [<Xn|SP>, #<simm>]!
- ST2G <Xt|SP>, [<Xn|SP>], #<simm>
- STZ2G <Xt|SP>, [<Xn|SP>, #<simm>]
- STZ2G <Xt|SP>, [<Xn|SP>, #<simm>]!
- STZ2G <Xt|SP>, [<Xn|SP>], #<simm>
In order to accept <Rt|SP> a new operand type Rt_SP is introduced which has
the same field as FLD_Rt but follows other semantics of Rn_SP.

[GAS, Arm] CLI with architecture sensitive extensions
This patch adds a new framework to add architecture sensitive extensions, like
GCC does. This patch also implements all architecture extensions currently
available in GCC.
This framework works as follows. To enable architecture sensitive extensions
for a particular architecture, that architecture must contain an ARM_ARCH_OPT2
entry in the 'arm_archs' table. All fields here are the same as previous, with
the addition of a new extra field at the end to <name> it's extension table.
This <name>, corresponds to a <name>_ext_table of type 'struct arm_ext_table'.
This struct can be filled with three types of entries:
ARM_ADD (string <ext>, arm_feature_set <enable_bits>), which means +<ext> will
enable <enable_bits>
ARM_REMOVE (string <ext>, arm_feature_set <disable_bits>), which means
+no<ext> will disable <disable_bits>
ARM_EXT (string <ext>, arm_feature_set <enable_bits>, arm_feature_set
<disable_bits>), which means +<ext> will enable <enable_bits> and +no<ext>
will disable <disable_bits> (this is to be used instead of adding an
ARM_ADD and ARM_REMOVE for the same <ext>)
This patch does not disable the use of the old extensions, even if some of them
are duplicated in the new tables. This is a "in-between-step" as we may want to
deprecate the old table of extensions in later patches. For now, GAS will first
look for the +<ext> or +no<ext> in the new table and if no entry is found it
will continue searching in the old table, following old behaviour. If only an
ARM_ADD or an ARM_REMOVE is defined for <ext> and +no<ext> or +<ext> resp. is
used then it also continues to search the old table for it.
A couple of caveats:
- This patch does not enable the use of these architecture extensions with the
'.arch_extension' directive. This is future work that I will tend to later.
- This patch does not enable the use of these architecture extensions with the
-mcpu option. This is future work that I will tend to later.
- This patch does not change the current behaviour when combining an
architecture extension and using -mfpu on the command-line. The current
behaviour of GAS is to stage the union of feature bits enabled by both -march
and -mfpu. GCC behaves differently here, so this is something we may want to
revisit on a later date.

[BFD, LD, AArch64, 2/3] Add --force-bti to enable BTI and to select BTI enabled PLTs
This is part of the patch series to add support for BTI and
PAC in AArch64 linker.
1) This patch adds a new ld command line option: --force-bti.
In the presence of this option, the linker enables BTI with the
GNU_PROPERTY_AARCH64_FEATURE_1_BTI feature. This gives out warning
in case of missing gnu notes for BTI in inputs.
2) It also defines a new set of BTI enabled PLTs. These are used either
when all the inputs are marked with GNU_PROPERTY_AARCH64_FEATURE_1_BTI
or when the new --force-bti option is used. This required adding new
fields in elf_aarch64_link_hash_table so that we could make the PLT
related information more generic.
3) It also defines a dynamic tag DT_AARCH64_BTI_PLT. The linker uses
this whenever it picks BTI enabled PLTs.
All these are made according to the new AArch64 ELF ABI
