4ad694eda1 Fix for #2063: The DllMain used in Cygwin did not run the thread memory 
pool cleanup upon THREAD_DETACH which is needed when compiled with
USE_TLS=1.

11cfd0bd75 Do not compile in AVX512 check if AVX support is disabled 
xgetbv is function depends on NO_AVX being undefined - we could change that too, but that combo is unlikely to work anyway

03a2bf2602 Fix potential memory leak in cpu enumeration on Linux (#2008) 
* Fix potential memory leak in cpu enumeration with glibc

An early return after a failed call to sched_getaffinity would leak the previously allocated cpu_set_t. Wrong calculation of the size argument in that call increased the likelyhood of that failure. Fixes #2003

69edc5bbe7 Restore dropped patches in the non-TLS branch of memory.c (#2004) 
* Restore dropped patches in the non-TLS branch of memory.c

As discovered in #2002, the reintroduction of the "original" non-TLS version of memory.c as an alternate branch had inadvertently used ba1f91f rather than a8002e2 , thereby dropping the commits for #1450, #1468, #1501, #1504 and #1520.

d5aeff636f ARM64: Enable DYNAMIC_ARCH 
Enable DYNAMIC_ARCH feature on ARM64. This patch uses the cpuid
feature in linux kernel to detect the core type at runtime
(https://www.kernel.org/doc/Documentation/arm64/cpu-feature-registers.txt).

If this feature is missing in kernel, then the user should use the
OPENBLAS_CORETYPE env variable to select the desired core type.

d50abc8903 ARM64: Move parameters from parameter.c to param.h

targets ARMV8, THUNDERX2T99. Instead set them as constants
in param.h at compile time.

21f46a1cf2 ARM64: Use THUNDERX2T99 Neon Kernels for ARMV8 
Currently the generic ARMV8 target uses C implementations
for many routines. Replace these with the neon implementations
written for THUNDERX2T99 target which are upto 6x faster for
certain routines.

6400868e55 Fix #1705 where we incorrectly calculate page locations. 
Since we now use an allocation size that isn't a multiple of PAGESIZE, finding
the pages for run_bench wasn't terminating properly.  Now we detect if we've
found enough pages for the allocation and terminate the loop.
