Work around windows/osx gcc12 x86_64 tree-optimizer problem and add an osx/gcc12 build to Azure CI (#3745)
Add pragma to disable the gcc tree-optimizer for some x86_64 S and Z kernels with gcc12 on OSX or Windows

Chen, Guobing e740c4873d Enable COOPERLAKE build target
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.

Arjan van de Ven 99c7bba8e4 Initial support for SkylakeX / AVX512
This patch adds the basic infrastructure for adding the SkylakeX (Intel Skylake server)
target. The SkylakeX target will use the AVX512 (AVX512VL level) instruction set,
which brings 2 basic things:
1) 512 bit wide SIMD (2x width of AVX2)
2) 32 SIMD registers (2x the number on AVX2)

This initial patch only contains a trivial transofrmation of the Haswell SGEMM kernel
to AVX512VL; more will follow later but this patch aims to get the infrastructure
in place for this "later".

Full performance tuning has not been done yet; with more registers and wider SIMD
it's in theory possible to retune the kernels but even without that there's an
interesting enough performance increase (30-40% range) with just this change.

Zhang Xianyi 6e7be06e07 Refs JuliaLang/julia#5728. Fix gemv performance bug on Haswell Mac OSX.
On Mac OS X, it should use .align 4 (equal to .align 16 on Linux).
I didn't get the performance benefit from .align. Thus, I deleted it.
