Use the skylake sgemm beta code also for haswell
...
with a few small changes it's possible to use the skylake sgemm code
also for haswell, this gives a modest gain (10% range) for smallish
matrixes but does wonders for very skinny matrixes

Add a "sgemm direct" mode for small matrixes

Add a "sgemm direct" mode for small matrixes
...
OpenBLAS has a fancy algorithm for copying the input data while laying
it out in a more CPU friendly memory layout.
This is great for large matrixes; the cost of the copy is easily
ammortized by the gains from the better memory layout.
But for small matrixes (on CPUs that can do efficient unaligned loads) this
copy can be a net loss.
This patch adds (for SKYLAKEX initially) a "sgemm direct" mode, that bypasses
the whole copy machinary for ALPHA=1/BETA=0/... standard arguments,
for small matrixes only.
What is small? For the non-threaded case this has been measured to be
in the M*N*K = 28 * 512 * 512 range, while in the threaded case it's
less, around M*N*K = 1 * 512 * 512

Fix two mistakes on Arm64 builds
...
* Falkor is an ARMv8.0 with ARMv8.1 features, and chosing armv8.1-a for
march generates instructions it cannot cope with. Reverting it back
to armv8-a.
* ThunderX2's build was left with a #define VULCAN, which made it miss
the right compiler flags in Makefile.arm64, although it did create
the right library in the end.
