add beta and alpha testcase for sbgemv

Add SBGEMVN Kernel for ARM64

Add sbgemv_t_bfdot kernel for ARM64

This improves performance for sbgemv_t by up to 100x on NEOVERSEV1.
The geometric mean speedup is ~61x for M=N=[2,512].

Make the Neoverse GEMM/GEMV throttling code conditional on SMP

dispatch NEOVERSEV2 to NEOVERSEN2 under dynamic setting

Add throttling profile for SGEMM and SGEMV on `NEOVERSEV2`

Fix "dummy2" flag reading in PPC970 S/DSCAL

Fix GEMMT transforming the input array B in some complex cases

Add ARM64 options for NVIDIA HPC

Support for SGEMM_DIRECT Kernel based on SME1

Ensure that gmake builds with flang-new link the flang runtime into the shared library

Fix the CMake build to define USE_TRMM for RISCV64 targets as well

Revert "Fix potential inaccuracy in multithreaded level3 related to SWITCH_RATIO"

CI: remove the express NeoverseN2 target from the Cobalt100 job in the gh workflow

* Added ARMV9SME target
* Added SGEMM_DIRECT kernel based on SME1

Refined GESV Parallelization Logic for Windows on ARM64

Add -O2 to flang flags when building on WoA in Release mode

LoongArch64: Fixed lapack test for LA264

Fix SGEMV on POWER8 by reverting to the non-vectorized earlier code

CirrusCI: Update FreeBSD jobs to 14.2

When the data type is single-precision real or single-precision complex,
converting it to double precision does not prevent overflow (as exposed in LAPACK tests).
The only solution is to follow C's approach: find the maximum value in the
array and divide each element by that maximum to avoid this issue

Fixed the error when the stride is zero

Do not check whether the input parameters c and s are zero,
as this may cause errors with special values (same as scal).
Although OpenBLAS's own test suite doesn't catch this, it will
cause LAPACK test cases to fail.
