Protection for the `xgetbv` instruction for systems that do not support
`xcr0` such as nehalem processors.
The `XSAVE` cpuid indicates support for `XSAVE`, `XRESTOR`, `XSETBV`,
`XGETBV` while `OSXSAVE` indicates if the operating system itself has
`XSAVE` turned on. Both must be checked at the same time.
* ARMeilleure: Add AVX512{F,VL,DQ,BW} detection
Add `UseAvx512Ortho` and `UseAvx512OrthoFloat` optimization flags as
short-hands for `F+VL` and `F+VL+DQ`.
* ARMeilleure: Add initial support for EVEX instruction encoding
Does not implement rounding, or exception controls.
* ARMeilleure: Add `X86Vpternlogd`
Accelerates the vector-`Not` instruction.
* ARMeilleure: Add check for `OSXSAVE` for AVX{2,512}
* ARMeilleure: Add check for `XCR0` flags
Add XCR0 register checks for AVX and AVX512F, following the guidelines
from section 14.3 and 15.2 from the Intel Architecture Software
Developer's Manual.
* ARMeilleure: Remove redundant `ReProtect` and `Dispose`, formatting
* ARMeilleure: Move XCR0 procedure to GetXcr0Eax
* ARMeilleure: Add `XCR0` to `FeatureInfo` structure
* ARMeilleure: Utilize `ReadOnlySpan` for Xcr0 assembly
Avoids an additional allocation
* ARMeilleure: Formatting fixes
* ARMeilleure: Fix EVEX encoding src2 register index
> Just like in VEX prefix, vvvv is provided in inverted form.
* ARMeilleure: Add `X86Vpternlogd` acceleration to `Vmvn_I`
Passes unit tests, verified instruction utilization
* ARMeilleure: Fix EVEX register operand designations
Operand 2 was being sourced improperly.
EVEX encoded instructions source their operands like so:
Operand 1: ModRM:reg
Operand 2: EVEX.vvvvv
Operand 3: ModRM:r/m
Operand 4: Imm
This fixes the improper register designations when emitting vpternlog.
Now "dest", "src1", "src2" arguments emit in the proper order in EVEX instructions.
* ARMeilleure: Add `X86Vpternlogd` acceleration to `Orn_V`
* ARMeilleure: PTC version bump
* ARMeilleure: Update EVEX encoding Debug.Assert to Debug.Fail
* ARMeilleure: Update EVEX encoding comment capitalization
* ARMeilleure: Add AVX512{F,VL,DQ,BW} detection
Add `UseAvx512Ortho` and `UseAvx512OrthoFloat` optimization flags as
short-hands for `F+VL` and `F+VL+DQ`.

Developer's Manual.
* ARMeilleure: Increment InternalVersion
* ARMeilleure: Remove redundant `ReProtect` and `Dispose`, formatting
* ARMeilleure: Move XCR0 procedure to GetXcr0Eax
* ARMeilleure: Add `XCR0` to `FeatureInfo` structure
* ARMeilleure: Utilize `ReadOnlySpan` for Xcr0 assembly
Avoids an additional allocation
* ARMeilleure: Formatting fixes
`MB` and `GB` can either be interpreted as having base-10 units, or
base-2. `MiB` and `GiB` removes this discrepancy so that units of memory
are always interpreted using base-2 units.
* ARMeilleure: Add `GFNI` detection
This is intended for utilizing the `gf2p8affineqb` instruction
* ARMeilleure: Add `gf2p8affineqb`
Not using the VEX or EVEX-form of this instruction is intentional. There
are `GFNI`-chips that do not support AVX(so no VEX encoding) such as
Tremont(Lakefield) chips as well as Jasper Lake.

* ARMeilleure: Add `gfni` acceleration of `Rbit_V`
Passes all `Rbit_V*` unit tests on my `i9-11900k`
* ARMeilleure: Add `gfni` acceleration of `S{l,r}i_V`
Also added a fast-path for when the shift amount is greater than the
size of the element.
* ARMeilleure: Add `gfni` acceleration of `Shl_V` and `Sshr_V`
* ARMeilleure: Increment InternalVersion
* ARMeilleure: Fix Intrinsic and Assembler Table alignment
`gf2p8affineqb` is the longest instruction name I know of. It shouldn't
get any wider than this.
* ARMeilleure: Remove SSE2+SHA requirement for GFNI
* ARMeilleure Add `X86GetGf2p8LogicalShiftLeft`
Used to generate GF(2^8) 8x8 bit-matrices for bit-shifting for the `gf2p8affineqb` instruction.
* ARMeilleure: Append `FeatureInfo7Ecx` to `FeatureInfo`
