Details: - Added 512-bit specific 'a64fx' subconfiguration that uses empirically tuned block size by Stepan Nassyr. This subconfig also sets the sector cache size and enables memory-tagging code in SVE gemm kernels. This subconfig utilizes (16, k) and (10, k) DPACKM kernels. - Added a vector-length agnostic 'armsve' subconfiguration that computes blocksizes according to the analytical model. This part is ported from Stepan Nassyr's repository. - Implemented vector-length-agnostic [d/s/sh] gemm kernels for Arm SVE at size (2*VL, 10). These kernels use unindexed FMLA instructions because indexed FMLA takes 2 FMA units in many implementations. PS: There are indexed-FLMA kernels in Stepan Nassyr's repository. - Implemented 512-bit SVE dpackm kernels with in-register transpose support for sizes (16, k) and (10, k). - Extended 256-bit SVE dpackm kernels by Linaro Ltd. to 512-bit for size (12, k). This dpackm kernel is not currently used by any subconfiguration. - Implemented several experimental dgemmsup kernels which would improve performance in a few cases. However, those dgemmsup kernels generally underperform hence they are not currently used in any subconfig. - Note: This commit squashes several commits submitted by RuQing Xu via PR #424.
