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.

e7366a4161 Restore the remaining utests (#1462) 
* Restore the remaining utests

* Try fork test on Cygwin and Linux only, it hangs on at least ARMv8/Android as well

* Use generic sswap/dswap kernels for NEHALEM 32bit to fix fault found by the restored swap utest

* Disable zdotu test for MS cl to work around runtime error -1073741819 on AppVeyor for now
(probably coding error in the initialization of the complex numbers or wrong choice of zdotu API)

2573311308 refs #140. Fixed zdot incompatibility ABI issue with GCC 4.7 on Win 32. 
GCC 4.7 uses MSVC ABI on Win 32. This means the caller pops the hidden pointer for returning
aggregate structures larger than 8 bytes.

7b410b7f0e Fixed #58 zdot SEGFAULT bug with GCC-4.6. Thank Mr. John for this patch. 
In i386 calling convention, the caller put the address of return value of zdot into the first hidden parameter.
Thus, the callee should delete this address before return.
Actually, I have fixed the same bug on x86/zdot_sse2.S (issue #32). However, that is not a good implementation which uses 3 instructions. Mr. John told me used "ret $0x4" to skip the first hidden address (4 bytes).
