* 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.13df339fe7/GenuineIntel/GenuineIntel00806A1_Lakefield_LC_InstLatX64.txt (L1297-L1299)13df339fe7/GenuineIntel/GenuineIntel00906C0_JasperLake_InstLatX64.txt (L1252-L1254)* 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`
