* 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
