* Add support for the Cray Fortran compiler

* Fix f2c-like support functions to compile with MSVC, and
re-enable C_LAPACK for MSVC in CMAKE

* Add MSVC&flang build to Azure CI in order to check C_LAPACK correctness

* Add C equivalents of the Fortran routines from Reference-LAPACK as fallbacks, and C_LAPACK variable to trigger their use

If no customized GEMM_SMALL_M_PERMIT kernel defined, it will just by pass to normal path.

Fix Cooperlake/DYNAMIC_ARCH builds with clang on Windows

Optimize the performance of dot by using universal intrinsics in X86/ARM

Make NO_AVX512 option override the AVX512 compile test in CMAKE builds as well

Enable new build target platform -- COOPERLAKE. This target platform
supports all the SKYLAKEX supported ISAs + avx512bf16. So all the
SKYLAKEX specific kernels/drivers and related code are now extended
to be also active on COOPERLAKE. Besides, new BF16 related kernels
are active under this target.

This patch adds support for bfloat16 data type matrix multiplication kernel.
For architectures that don't support bfloat16, it is defined as unsigned short
(2 bytes).  Default unroll sizes can be changed as per architecture as done for
SGEMM and for now 8 and 4 are used for M and N.  Size of ncopy/tcopy can be
changed as per architecture requirement and for now, size 2 is used.

Added shgemm in kernel/power/KERNEL.POWER9 and tested in powerpc64le and
powerpc64.  For reference, added a small test compare_sgemm_shgemm.c to compare
sgemm and shgemm output.

This patch does not cover OpenBLAS test, benchmark and lapack tests for shgemm.
Complex type implementation can be discussed and added once this is approved.

(and other small fixes to match Makefile behaviour)

21eda8b5 introduced a check in getarch.c to test if the compiler is capable of
AVX512. This check currently fails, since the used __AVX2__ macro is only
defined if getarch itself was compiled with AVX2/AVX512 support. Make sure this
is the case by building getarch with -march=native on x86_64. It is only
supposed to run on the build host anyway.
