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.

5b708e5eb1 sgemm/dgemm: add a way for an arch kernel to specify prefered sizes 
The current gemm threading code can make very unfortunate choices, for
example on my 10 core system a 1024x1024x1024 matrix multiply ends up
chunking into blocks of 102... which is not a vector friendly size
and performance ends up horrible.

this patch adds a helper define where an architecture can specify
a preference for size multiples.
This is different from existing defines that are minimum sizes and such.

The performance increase with this patch for the 1024x1024x1024 sgemm
is 2.3x (!!)

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.

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.
