There were a couple of issues with the detection code used to check
for RVV 1.0 on kernels that do not support hwprobe.

1. The vtype clobber was missing
2. The wrong form of vsetvli was being used. The vsetvli x0, x0 form
   is inappropriate for this use case as it can only be safely used
   in code where the value of vtype is known.  The use of vsetvli
   x0, x0 here can lead to a failure to detect RVV 1.0, if,
   for example, the vill bit happens to be set before
   detect_riscv64_rvv100 is called.

We fix both issues by adding the missing clobber and replacing the
first parameter to vsetvli with t0 (which we add to our clobbers).

- Sets up all the various entrypoints for `bgemv`
- Adds `bscal` for use in the `bgemv` interface
- Adds test cases for comparing `sgemv` and `bgemv`
- Adds generic kernels for `bgemv_n` and `bgemv_t` which are accurate
enough to pass above tests

This fixes the build and tests on `NEOVERSEV1` target, which was failing
with specific constants for `SBGEMM`

Setting up all the infrastructure for BGEMM support in OpenBLAS, hopefully I found all the right places.

Fix SBGEMM BFLOAT16 build

Add Support for POWER11

A64FX.

Exit if memory allocation keeps failing, instead of retrying forever

When there are multiple NUMA nodes and hyper-threading causes adjacent logical cores to share a physical core (e.g., common -> avail[i] = 0x5555555555555555UL), the numa_mapping function should not use a bitmask for filtering, as this would lead to redundant masking with the subsequent local_cpu_map function.

Add support for FP16 to openBLAS and shgemm on RISCV

Added HFLOAT16 support for RISCV64
Added shgemm_kernel_8x8 for RISCV64_ZVL128B and shgemm_kernel_16x8 for RISCV64_ZVL256B based on HFLOAT16
The instruction sets used are ZVFH and ZFH, which need to be supported by RVV1.0

* Fix ARMV9SME target and add support_sme1 code for MacOS
* make sgemm_direct unconditionally available on all arm64
* build a (dummy) sgemm_direct kernel on all arm64





* Update dynamic_arm64.c

Using `OpenMP::OpenMP_LANG` targets for CMake is less error-prone than
passing the compiler and linker flags manually. Furthermore, it allows
the user to customize those flags by setting `OpenMP_LANG_FLAGS`,
`OpenMP_LANG_LIB_NAMES`, and `OpenMP_omp_LIBRARY`.

* Tighten memory orders for C11 atomic operations

dispatch NEOVERSEV2 to NEOVERSEN2 under dynamic setting

Support for SGEMM_DIRECT Kernel based on SME1

* Added ARMV9SME target
* Added SGEMM_DIRECT kernel based on SME1

The warning was:

The added define is the same as is already present in the TLS part of
`memory.c`. This follows up on gh-4681.

The use of `volatile` for `newmemstruct` seems on purpose, and there are
more such constructs in this file. The warning appeared after gh-4451
and is correct. The `free` prototype doesn't expect a volatile pointer,
hence this change adds a cast to silence the warning.

LoongArch64: Enable cmake cross-compilation

Use microarchitecture name instead of meaningless strings to name the core,
the legacy core is still retained.
1. Rename LOONGSONGENERIC to LA64_GENERIC
2. Rename LOONGSON3R5 to LA464
3. Rename LOONGSON2K1000 to LA264

Ensure a memory buffer has been allocated for each thread before invoking it (take 2)
